Mark file system inode and similar slab caches subject to SLAB_MEM_SPREAD memory spreading. If a slab cache is marked SLAB_MEM_SPREAD, then anytime that a task that's in a cpuset with the 'memory_spread_slab' option enabled goes to allocate from such a slab cache, the allocations are spread evenly over all the memory nodes (task->mems_allowed) allowed to that task, instead of favoring allocation on the node local to the current cpu. The following inode and similar caches are marked SLAB_MEM_SPREAD: file cache ==== ===== fs/adfs/super.c adfs_inode_cache fs/affs/super.c affs_inode_cache fs/befs/linuxvfs.c befs_inode_cache fs/bfs/inode.c bfs_inode_cache fs/block_dev.c bdev_cache fs/cifs/cifsfs.c cifs_inode_cache fs/coda/inode.c coda_inode_cache fs/dquot.c dquot fs/efs/super.c efs_inode_cache fs/ext2/super.c ext2_inode_cache fs/ext2/xattr.c (fs/mbcache.c) ext2_xattr fs/ext3/super.c ext3_inode_cache fs/ext3/xattr.c (fs/mbcache.c) ext3_xattr fs/fat/cache.c fat_cache fs/fat/inode.c fat_inode_cache fs/freevxfs/vxfs_super.c vxfs_inode fs/hpfs/super.c hpfs_inode_cache fs/isofs/inode.c isofs_inode_cache fs/jffs/inode-v23.c jffs_fm fs/jffs2/super.c jffs2_i fs/jfs/super.c jfs_ip fs/minix/inode.c minix_inode_cache fs/ncpfs/inode.c ncp_inode_cache fs/nfs/direct.c nfs_direct_cache fs/nfs/inode.c nfs_inode_cache fs/ntfs/super.c ntfs_big_inode_cache_name fs/ntfs/super.c ntfs_inode_cache fs/ocfs2/dlm/dlmfs.c dlmfs_inode_cache fs/ocfs2/super.c ocfs2_inode_cache fs/proc/inode.c proc_inode_cache fs/qnx4/inode.c qnx4_inode_cache fs/reiserfs/super.c reiser_inode_cache fs/romfs/inode.c romfs_inode_cache fs/smbfs/inode.c smb_inode_cache fs/sysv/inode.c sysv_inode_cache fs/udf/super.c udf_inode_cache fs/ufs/super.c ufs_inode_cache net/socket.c sock_inode_cache net/sunrpc/rpc_pipe.c rpc_inode_cache The choice of which slab caches to so mark was quite simple. I marked those already marked SLAB_RECLAIM_ACCOUNT, except for fs/xfs, dentry_cache, inode_cache, and buffer_head, which were marked in a previous patch. Even though SLAB_RECLAIM_ACCOUNT is for a different purpose, it marks the same potentially large file system i/o related slab caches as we need for memory spreading. Given that the rule now becomes "wherever you would have used a SLAB_RECLAIM_ACCOUNT slab cache flag before (usually the inode cache), use the SLAB_MEM_SPREAD flag too", this should be easy enough to maintain. Future file system writers will just copy one of the existing file system slab cache setups and tend to get it right without thinking.

The meaning of MS_VERBOSE is backwards; if the bit is set, it really means, "don't be verbose". This is confusing and counter-intuitive. In addition, there is also no way to set the MS_VERBOSE flag in the mount(8) program in util-linux, but interesting, it does define options which would do the right thing if MS_SILENT were defined, which unfortunately we do not: #ifdef MS_SILENT { "quiet", 0, 0, MS_SILENT }, /* be quiet */ { "loud", 0, 1, MS_SILENT }, /* print out messages. */ #endif So the obvious fix is to deprecate the use of MS_VERBOSE and replace it with MS_SILENT.

session when multiply mounted. Fixes slow response when cifs client is mounted to shares on multiple servers and oplock break occurs (usually due to attempt to multiply open a file). When treeids on mutiple mounted shares match and we find the wrong match first, we searched for the wrong cached files to send oplock break response for which usually meant that no matching file was found and thus the server would have to timeout the notification. Oplock break timeout is about 20 seconds on some servers so this could cause significantly slower performance on file open calls in a few cases (in particular when multiple shares are mounted from multiple servers, tree ids match, and we have a cached file which is later opened multiple times). This was the most important of the bugs that was found and fixed at Connectathon (interoperability testing event) this week.

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.

patch 2ea55c01e0c5dfead8699484b0bae2a375b1f61c fixed CIFS clobbering the global fops structure for some per mount setting, by duplicating and having 2 fops structs. However the write to the fops was left behind, which is a NOP in practice (due to the fact that we KNOW the fops has that field set to NULL already due to the duplication). So remove it...

writev and aio_write to flush properly. This is Christoph's patch merged with the new nobrl file operations Signed-off-by: NDave 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..
