2007-02-12[PATCH] mark struct file_operations const 6Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2007-02-05[GFS2] make lock_dlm drop_count tunable in sysfsDavid Teigland
We want to be able to change or disable the default drop_count (number at which the dlm asks gfs to limit the the number of locks it's holding). Add it to the collection of sysfs tunables for an fs.

2007-02-05[GFS2] increase default lock limitDavid Teigland
Increase the number of locks at which point the dlm begins asking gfs to reduce its lock usage. The default value is largely arbitrary, but the current value of 50,000 ends up limiting performance unnecessarily for too many users.

2006-09-27[GFS2] Fix bug in Makefiles for lock modulesSteven Whitehouse
The Makefile had the wrong CONFIG_ variable in it so that in case GFS2 was y and the lock modules were m, they were not getting built properly. 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.

2006-09-08[GFS2] Use void * instead of typedef for locking module interfaceSteven Whitehouse
As requested by Jan Engelhardt, this removes the typedefs in the locking module interface and replaces them with void *. Also since we are changing the interface, I've added a few consts as well.

2006-09-07[GFS2] Remove unused sync_lvb code from lock modulesSteven Whitehouse
This code is no longer used for anything and can be removed from the locking modules. The sync_lvb function is not required as this happens automatically with the current locking system. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-09-07[GFS2] Remove one typedefSteven Whitehouse
This removes one of the typedefs from the locking interface. It is replaced by a forward declaration of the gfs2 superblock. The other two are not so easy to solve since in their case, they can refer to one of two possible structures.

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.

2006-08-07[GFS2] match plock result with correct requestDavid Teigland
When the result of a posix lock request is read it needs to be matched up with the correct waiting request. The owner field needs to be used in the comparison since more than one process may be waiting for locks on the same file.

2006-08-07[GFS2] lockproto api prefixDavid Teigland

2006-07-31[GFS2] add plock ownerDavid Teigland

2006-03-31[GFS2] Update GFS2 for the recent pull from LinusSteven Whitehouse
Some interfaces have changed. In particular one of the posix locking functions has changed prototype, along with the address space operation invalidatepage and the block getting callback to the direct IO function. In addition add the splice file operations. These will need to be updated to support AOP_TRUNCATED_PAGE before they will be of much use to us. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
