* xfs: remove subdirectoriesChristoph Hellwig2011-08-12
| | | | | | | | | | | | Use the move from Linux 2.6 to Linux 3.x as an excuse to kill the annoying subdirectories in the XFS source code. Besides the large amount of file rename the only changes are to the Makefile, a few files including headers with the subdirectory prefix, and the binary sysctl compat code that includes a header under fs/xfs/ from kernel/.

* xfs: merge iop_unpin_remove into iop_unpinChristoph Hellwig2010-07-26
| | | | | | | | | | | The unpin_remove item operation instances always share most of the implementation with the respective unpin implementation. So instead of keeping two different entry points add a remove flag to the unpin operation and share the code more easily.

* xfs: drop dmapi hooksChristoph Hellwig2010-07-26
| | | | | | | | | | | | | | Dmapi support was never merged upstream, but we still have a lot of hooks bloating XFS for it, all over the fast pathes of the filesystem. This patch drops over 700 lines of dmapi overhead. If we'll ever get HSM support in mainline at least the namespace events can be done much saner in the VFS instead of the individual filesystem, so it's not like this is much help for future work.

* xfs: remove stale parameter from ->iop_unpin methodDave Chinner2010-05-19
| | | | | | | | | | | | | The staleness of a object being unpinned can be directly derived from the object itself - there is no need to extract it from the object then pass it as a parameter into IOP_UNPIN(). This means we can kill the XFS_LID_BUF_STALE flag - it is set, checked and cleared in the same places XFS_BLI_STALE flag in the xfs_buf_log_item so it is now redundant and hence safe to remove.

| | | | | | | | | | | | | | dquots are never flushed asynchronously. Remove the flag and the async write support from the flush function.

* xfs: Don't issue buffer IO direct from AIL push V2Dave Chinner2010-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | All buffers logged into the AIL are marked as delayed write. When the AIL needs to push the buffer out, it issues an async write of the buffer. This means that IO patterns are dependent on the order of buffers in the AIL. Instead of flushing the buffer, promote the buffer in the delayed write list so that the next time the xfsbufd is run the buffer will be flushed by the xfsbufd. Return the state to the xfsaild that the buffer was promoted so that the xfsaild knows that it needs to cause the xfsbufd to run to flush the buffers that were promoted. Using the xfsbufd for issuing the IO allows us to dispatch all buffer IO from the one queue. This means that we can make much more enlightened decisions on what order to flush buffers to disk as we don't have multiple places issuing IO. Optimisations to xfsbufd will be in a future patch. Version 2 - kill XFS_ITEM_FLUSHING as it is now unused. Signed-off-by: Dave Chinner <david@fromorbit.com> Reviewed-by: Christoph Hellwig <hch@lst.de>

Split xfs_log_force into a two helpers - xfs_log_force which forces the whole log, and xfs_log_force_lsn which forces up to the specified LSN. The underlying implementations already were entirely separate, as were the users. Also re-indent the new _xfs_log_force/_xfs_log_force which previously had a weird coding style.

| | | | | | | | | | | | This patch rips out the XFS ACL handling code and uses the generic fs/posix_acl.c code instead. The ondisk format is of course left unchanged.

* [XFS] Finish removing the mount pointer from the AIL APIDavid Chinner2008-10-30
| | | | | | | | | | | | | | | | | | Change all the remaining AIL API functions that are passed struct xfs_mount pointers to pass pointers directly to the struct xfs_ail being used. With this conversion, all external access to the AIL is via the struct xfs_ail. Hence the operation and referencing of the AIL is almost entirely independent of the xfs_mount that is using it - it is now much more tightly tied to the log and the items it is tracking in the log than it is tied to the xfs_mount.

| | | | | | | | | | | | | | | | | | | | | | | This is a code cleanup and optimization that removes a per mount point spinlock from the quota code and cleans up the code. The patch changes the pincount from being an int protected by a spinlock to an atomic_t allowing the pincount to be manipulated without holding the spinlock. This cleanup also protects against random wakup's of both the aild and xfssyncd by reevaluating the pincount after been woken. Two latter patches will address the Spurious wakeups.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.
