2006-11-30[GFS2] Shrink gfs2_inode (4) - di_uid/di_gidSteven Whitehouse
Remove duplicate di_uid/di_gid fields in favour of using inode->i_uid/inode->i_gid instead. This saves 8 bytes. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-11-30[GFS2] Shrink gfs2_inode (3) - di_modeSteven Whitehouse
This removes the duplicate di_mode field in favour of using the inode->i_mode field. This saves 4 bytes. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-11-30[GFS2] Shrink gfs2_inode (2) - di_major/di_minorSteven Whitehouse
This removes the device numbers from this structure by using inode->i_rdev instead. It also cleans up the code in gfs2_mknod. It results in shrinking the gfs2_inode by 8 bytes. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-11-30[GFS2] Change argument to gfs2_dinode_printSteven Whitehouse
Change argument for gfs2_dinode_print in order to prepare for removal of duplicate fields between struct inode and struct gfs2_dinode_host. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-11-30[GFS2] Change argument of gfs2_dinode_outSteven Whitehouse
Everywhere this was called, a struct gfs2_inode was available, but despite that, it was always called with a struct gfs2_dinode as an argument. By making this change it paves the way to start eliminating fields duplicated between the kernel's struct inode and the struct gfs2_dinode. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

2006-09-25[GFS2/DLM] Fix trailing whitespaceSteven Whitehouse
As per Andrew Morton's request, removed trailing whitespace. Cc: Andrew Morton <akpm@osdl.org> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-09-19[GFS2] Export lm_interface to kernel headersFabio Massimo Di Nitto
lm_interface.h has a few out of the tree clients such as GFS1 and userland tools. Right now, these clients keeps a copy of the file in their build tree that can go out of sync. Move lm_interface.h to include/linux, export it to userland and clean up fs/gfs2 to use the new location. Signed-off-by: Fabio M. Di Nitto <fabbione@ubuntu.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-09-04[GFS2] More code style updatesSteven Whitehouse
As per Jan Engelhardt's fifth email. This has most of the changes recommended, which is the removal of casts which are not required, some indenting fixes and similar. Cc: Jan Engelhardt <jengelh@linux01.gwdg.de> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-09-04[GFS2] Change all types to uX styleSteven Whitehouse
This makes all fixed size types have consistent names. Cc: Jan Engelhardt <jengelh@linux01.gwdg.de> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-09-04[GFS2] Align all labels against LH sideSteven Whitehouse
This makes everything consistent. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-09-01[GFS2] Update copyright, tidy up incore.hSteven Whitehouse
As per comments from Jan Engelhardt <jengelh@linux01.gwdg.de> this updates the copyright message to say "version" in full rather than "v.2". Also incore.h has been updated to remove forward structure declarations which are not required. The gfs2_quota_lvb structure has now had endianess annotations added to it. Also quota.c has been updated so that we now store the lvb data locally in endian independant format to avoid needing a structure in host endianess too. As a result the endianess conversions are done as required at various points and thus the conversion routines in lvb.[ch] are no longer required. I've moved the one remaining constant in lvb.h thats used into lm.h and removed the unused lvb.[ch]. I have not changed the HIF_ constants. That is left to a later patch which I hope will unify the gh_flags and gh_iflags fields of the struct gfs2_holder.

2006-07-26[GFS2] Remove page.[ch]Steven Whitehouse
The remaining routines in page.c were all only used in one other file, so they are now moved into the files where they are referenced and made static. Thus page.[ch] are no longer required. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-07-06[GFS2] Fixes to scanning of glocks (again)Steven Whitehouse
This really is the correct fix this time. We just ignore all glocks associated with inodes until the inodes are pushed from the inode cache. At that point the glocks are queued for reclaim, so we don't need to do it here. Also fix one or two other minor bugs. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-06-24[GFS2] Eliminate one instance of __GFP_NOFAILSteven Whitehouse
This removes one instance of GFP_NOFAIL from the glock callback function. It also fixes a bug where a , was used at a line end rather than ; causing unintended results. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-06-22[GFS2] Remove gfs2_repermissionSteven Whitehouse
gfs2_repermission is just a wrapper for permission, so remove it and call permission directly where required. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-06-21[GFS2] Fix double locking problem in renameSteven Whitehouse
The rename inode operation was trying to lock the same inode twice in the case of renaming with the source and destination directories the same. We now test for this and just lock once. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-06-19[GFS2] Remove debugging printksSteven Whitehouse
A few of my printks slipped through last time. Also fix a couple of minor bugs. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-06-14[GFS2] Fix unlinked file handlingSteven Whitehouse
This patch fixes the way we have been dealing with unlinked, but still open files. It removes all limits (other than memory for inodes, as per every other filesystem) on numbers of these which we can support on GFS2. It also means that (like other fs) its the responsibility of the last process to close the file to deallocate the storage, rather than the person who did the unlinking. Note that with GFS2, those two events might take place on different nodes. Also there are a number of other changes: o We use the Linux inode subsystem as it was intended to be used, wrt allocating GFS2 inodes o The Linux inode cache is now the point which we use for local enforcement of only holding one copy of the inode in core at once (previous to this we used the glock layer). o We no longer use the unlinked "special" file. We just ignore it completely. This makes unlinking more efficient. o We now use the 4th block allocation state. The previously unused state is used to track unlinked but still open inodes. o gfs2_inoded is no longer needed o Several fields are now no longer needed (and removed) from the in core struct gfs2_inode o Several fields are no longer needed (and removed) from the in core superblock There are a number of future possible optimisations and clean ups which have been made possible by this patch.

2006-05-18[GFS2] Remove semaphore.h from C filesSteven Whitehouse
We no longer use semaphores, everything has been converted to mutex or rwsem, so we don't need to include this header any more. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-05-18[GFS2] Drop log lock on I/O error & tidy upSteven Whitehouse
This patch drops the log spinlock when an I/O error occurs to avoid any possible problems in case of blocking or recursion in the I/O error routine. It also has a few cosmetic changes to tidy up various other files. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-04-18[GFS2] Use vmalloc() in dir codeSteven Whitehouse
When allocating memory to sort directory entries, use vmalloc() rather than kmalloc() since for larger directories, the required size can easily be graeter than the 128k maximum of kmalloc(). Also adding the first steps towards getting the AOP_TRUNCATED_PAGE return code get in the glock code by flagging all places where we request a glock and we are holding a page lock. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-03-28[GFS2] Further updates to dir and logging codeSteven Whitehouse
This reduces the size of the directory code by about 3k and gets readdir() to use the functions which were introduced in the previous directory code update. Two memory allocations are merged into one. Eliminates zeroing of some buffers which were never used before they were initialised by other data. There is still scope for further improvement in the directory code. On the logging side, a hand created mutex has been replaced by a standard Linux mutex in the log allocation code.

2006-03-20[GFS2] Fix bug in directory code and tidy upSteven Whitehouse
Due to a typo, the dir leaf split operation was (for the first split in a directory) writing the new hash vaules at the wrong offset. This is now fixed. Also some other tidy ups are included: - We use GFS2's hash function for dentries (see ops_dentry.c) so that we don't have to keep recalculating the hash values. - A lot of common code is eliminated between the various directory lookup routines. - Better error checking on directory lookup (previously different routines checked for different errors) - The leaf split operation has a couple of redundant operations removed from it, so it should be faster. There is still further scope for further clean ups in the directory code, and readdir in particular could do with slimming down a bit. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-02-27[GFS2] Macros removal in gfs2.hSteven Whitehouse
As suggested by Pekka Enberg <penberg@cs.helsinki.fi>. The DIV_RU macro is renamed DIV_ROUND_UP and and moved to kernel.h The other macros are gone from gfs2.h as (although not requested by Pekka Enberg) are a number of included header file which are now included individually. The inode number comparison function is now an inline function. The DT2IF and IF2DT may be addressed in a future patch. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

2006-02-13[GFS2] Fix for root inode ref count bugSteven Whitehouse
Umount is now working correctly again. The bug was due to not getting an extra ref count when mounting the fs. We should have bumped it by two (once for the internal pointer to the root inode from the super block and once for the inode hanging off the dcache entry for root). Also this patch tidys up the code dealing with looking up and creating inodes. We now pass Linux inodes (with gfs2_inodes attached) rather than the other way around and this reduces code duplication in various places. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-01-24[GFS2] Remove pointless argument relating to truncateSteven Whitehouse
For some reason a function pointer was being passed through the truncate code which only ever took one value. This removes the function pointer and replaces it with a single call to the function in question. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-01-18[GFS2] Add an additional argument to gfs2_trans_add_bh()Steven Whitehouse
This adds an extra argument to gfs2_trans_add_bh() to indicate whether the bh being added to the transaction is metadata or data. Its currently unused since all existing callers set it to 1 (metadata) but following patches will make use of it. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
