2006-01-08[PATCH] Fix and add EXPORT_SYMBOL(filemap_write_and_wait)OGAWA Hirofumi
This patch add EXPORT_SYMBOL(filemap_write_and_wait) and use it. See mm/filemap.c: And changes the filemap_write_and_wait() and filemap_write_and_wait_range(). Current filemap_write_and_wait() doesn't wait if filemap_fdatawrite() returns error. However, even if filemap_fdatawrite() returned an error, it may have submitted the partially data pages to the device. (e.g. in the case of -ENOSPC) <quotation> Andrew Morton writes, If filemap_fdatawrite() returns an error, this might be due to some I/O problem: dead disk, unplugged cable, etc. Given the generally crappy quality of the kernel's handling of such exceptions, there's a good chance that the filemap_fdatawait() will get stuck in D state forever. </quotation> So, this patch doesn't wait if filemap_fdatawrite() returns the -EIO. Trond, could you please review the nfs part? Especially I'm not sure, nfs must use the "filemap_fdatawrite(inode->i_mapping) == 0", or not.

2005-11-29[CIFS] Fix umount --force to wake up the pending response queue, not justSteve French
the request queue. Also periodically wakeup response_q so threads can check if stuck requests have timed out. Workaround Windows server illegal smb length on transact2 findfirst response. Signed-off-by: Steve French <sfrench@us.ibm.com>
2005-11-29[CIFS] Fix missing permission check on setattr when noperm mount option isSteve French
disabled. Also set mode, uid, gid better on mkdir and create for the case when Unix Extensions is not enabled and setuids is enabled. This is necessary to fix the hole in which chown could be allowed for non-root users in some cases if root mounted, and also to display the mode and uid properly in some cases.

2005-11-28[CIFS] When file is deleted locally but later recreated on the serverSteve French
fix cifs negative dentries so they are freed faster (not requiring umount or readdir e.g.) so the client recognizes the new file on the server more quickly. Signed-off-by: Steve French <sfrench@us.ibm.com>
2005-11-19[CIFS] Fix setattr of mode only (e.g. in some chmod cases) to WindowsSteve French

2005-11-17[CIFS] Vectored and async i/o turned on and correct theSteve French
writev and aio_write to flush properly. This is Christoph's patch merged with the new nobrl file operations Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com> From: Christoph Hellwig <hch@lst.de> - support vectored and async aio ops unconditionally - this is above the pagecache and transparent to the fs - remove cifs_read_wrapper. it was only doing silly checks and calling generic_file_write in all cases. - use do_sync_read/do_sync_write as read/write operations. They call ->readv/->writev which we now always implemente. - add the filemap_fdatawrite calls to writev/aio_write which were missing previously compared to plain write. no idea what the point behind them is, but let's be consistent at least..

2005-10-27[CIFS] Change pragma pack(1) to attribute(packed) to allow cifs on arm to accessSteve French
unaligned structures coming in off the wire gcc on arm processors generates very odd code with pragma pack specified - although it does pack the structures in some sense - it does not allow you to access unaligned elements in nested structures at the right offset as other architectures do. Oddly enough though, specifying the structures as packed the long way - one by one with the packed attribute does work. Rather than fighting over whether this is a gcc bug or some obscure side effect of pragma pack, it is easier to do what most (all but 96 other places in the kernel) do - and replace pragma pack with dozens of attribute(packed) structure qualifiers. Much more verbose ... but at least it works.
