* [XFS] split xfs_ioc_xattrLachlan McIlroy2008-04-17
| | | | | | | | | | | The three subcases of xfs_ioc_xattr don't share any semantics and almost no code, so split it into three separate helpers.

* [XFS] don't encode parent in nfs filehandles unless nessecaryChristoph Hellwig2008-04-17
| | | | | | | | | | | | | As Dave pointed out after the export ops changes we now always encode the parent into the filehandle for regular files, but it's not actually needed when the filesystem is export with no_subtree_check. This one-liner fixes xfs_fs_encode_fh to skip encoding the parent unless nessecary.

* [XFS] Don't block pdflush when writing back inodesDavid Chinner2008-04-17
| | | | | | | | | | | | | | | | | | | | | | | | When pdflush is writing back inodes, it can get stuck on inode cluster buffers that are currently under I/O. This occurs when we write data to multiple inodes in the same inode cluster at the same time. Effectively, delayed allocation marks the inode dirty during the data writeback. Hence if the inode cluster was flushed during the writeback of the first inode, the writeback of the second inode will block waiting for the inode cluster write to complete before writing it again for the newly dirtied inode. Basically, we want to avoid this from happening so we don't block pdflush and slow down all of writeback. Hence we introduce a non-blocking async inode flush flag that pdflush uses. If this flag is set, we use non-blocking operations (e.g. try locks) whereever we can to avoid blocking or extra I/O being issued.

* [XFS] If you mount an XFS filesystem with no mount options at all, thenJosef Jeff Sipek2008-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the "ikeep" option is set rather than "noikeep". This regression was introduced in 970451. With no mount options specified, xfs_parseargs() does the following: int ikeep = 0; args->flags |= XFSMNT_BARRIER; args->flags2 |= XFSMNT2_COMPAT_IOSIZE; if (!options) goto done; It only sets the above two options by default and before, it also used to set XFSMNT_IDELETE by default. If options are specified, then if (!(args->flags & XFSMNT_DMAPI) && !ikeep) args->flags |= XFSMNT_IDELETE; is executed later on which is skipped by the "goto done;" above. The solution is to invert the logic.

* Embed a struct path into struct nameidata instead of nd->{dentry,mnt}Jan Blunck2008-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the central patch of a cleanup series. In most cases there is no good reason why someone would want to use a dentry for itself. This series reflects that fact and embeds a struct path into nameidata. Together with the other patches of this series - it enforced the correct order of getting/releasing the reference count on <dentry,vfsmount> pairs - it prepares the VFS for stacking support since it is essential to have a struct path in every place where the stack can be traversed - it reduces the overall code size: without patch series: text data bss dec hex filename 5321639 858418 715768 6895825 6938d1 vmlinux with patch series: text data bss dec hex filename 5320026 858418 715768 6894212 693284 vmlinux This patch: Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

| * [XFS] Move AIL pushing into it's own threadDavid Chinner2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When many hundreds to thousands of threads all try to do simultaneous transactions and the log is in a tail-pushing situation (i.e. full), we can get multiple threads walking the AIL list and contending on the AIL lock. The AIL push is, in effect, a simple I/O dispatch algorithm complicated by the ordering constraints placed on it by the transaction subsystem. It really does not need multiple threads to push on it - even when only a single CPU is pushing the AIL, it can push the I/O out far faster that pretty much any disk subsystem can handle. So, to avoid contention problems stemming from multiple list walkers, move the list walk off into another thread and simply provide a "target" to push to. When a thread requires a push, it sets the target and wakes the push thread, then goes to sleep waiting for the required amount of space to become available in the log. This mechanism should also be a lot fairer under heavy load as the waiters will queue in arrival order, rather than queuing in "who completed a push first" order. Also, by moving the pushing to a separate thread we can do more effectively overload detection and prevention as we can keep context from loop iteration to loop iteration. That is, we can push only part of the list each loop and not have to loop back to the start of the list every time we run. This should also help by reducing the number of items we try to lock and/or push items that we cannot move. Note that this patch is not intended to solve the inefficiencies in the AIL structure and the associated issues with extremely large list contents. That needs to be addresses separately; parallel access would cause problems to any new structure as well, so I'm only aiming to isolate the structure from unbounded parallelism here.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The log force added in xfs_iget_core() has been a performance issue since it was introduced for tight loops that allocate then unlink a single file. under heavy writeback, this can introduce unnecessary latency due tothe log I/o getting stuck behind bulk data writes. Fix this latency problem by avoinding the need for the log force by moving the place we mark linux inode dirty to the transaction commit rather than on transaction completion. This also closes a potential hole in the sync code where a linux inode is not dirty between the time it is modified and the time the log buffer has been written to disk.

| * [XFS] fix 32-bit compat ioctls for GETXFLAGS, SETXFLAGS, GETVERSIONEric Sandeen2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | XFS_IOC_GETVERSION, XFS_IOC_GETXFLAGS and XFS_IOC_SETXFLAGS all take a "long" which changes size between 32 and 64 bit platforms. So, the ioctl cmds that come in from a 32-bit app aren't as expected, for example on GETXFLAGS, unknown cmd fd(3) cmd(80046601){t:'f';sz:4} due to the size mismatch. So, use instead the 32-bit version of the commands for compat ioctls, and other than that it doesn't take any more manipulation. Also, for both native and compat versions, just define them to the values as defined in fs.h SGI-PV: 971186 SGI-Modid: xfs-linux-melb:xfs-kern:29849a Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com> Signed-off-by: Tim Shimmin <tes@sgi.com>
| * [XFS] kill superflous buffer lockingChristoph Hellwig2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no need to lock any page in xfs_buf.c because we operate on our own address_space and all locking is covered by the buffer semaphore. If we ever switch back to main blockdeive address_space as suggested e.g. for fsblock with a similar scheme the locking will have to be totally revised anyway because the current scheme is neither correct nor coherent with itself.

| | | | | | | | | | | | | | | | | | | | | | | | | | xfs_ioctl.c passes around vnode pointers quite a lot, but all places already have the Linux inode which is identical to the vnode these days. Clean the code up to always use the Linux inode.

| * [XFS] Kill off xfs_statvfs.Christoph Hellwig2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were already filling the Linux struct statfs anyway, and doing this trivial task directly in xfs_fs_statfs makes the code quite a bit cleaner. While I was at it I also moved copying attributes that don't change over the lifetime of the filesystem outside the superblock lock. xfs_fs_fill_super used to get the magic number and blocksize through xfs_statvfs, but assigning them directly is a lot cleaner and will save some stack space during mount.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xfs_iocore_t is a structure embedded in xfs_inode. Except for one field it just duplicates fields already in xfs_inode, and there is nothing this abstraction buys us on XFS/Linux. This patch removes it and shrinks source and binary size of xfs aswell as shrinking the size of xfs_inode by 60/44 bytes in debug/non-debug builds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there is an indirection called ioops in the XFS data I/O path. Various functions are called by functions pointers, but there is no coherence in what this is for, and of course for XFS itself it's entirely unused. This patch removes it instead and significantly reduces source and binary size of XFS while making maintaince easier.
