xfs: remove subdirectories

2011-08-12T21:21:35+00:00

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: don't expect xfs headers to be in subdirectories

2011-08-12T18:57:55+00:00

Fix up some #include directives in preparation for moving a few header files out of xfs source subdirectories. Note that "xfs_linux.h" also got its quoting convention for included files switched. Signed-off-by: Alex Elder Reviewed-by: Christoph Hellwig

xfs: use generic get_unaligned_beXX helpers

2011-07-08T12:35:58+00:00

Switch the shortform directory code over to use the generic get_unaligned_beXX helpers instead of reinventing them. As a result kill off xfs_arch.h and move the setting of XFS_NATIVE_HOST into xfs_linux.h. Signed-off-by: Christoph Hellwig Reviewed-by: Alex Elder Reviewed-by: Dave Chinner

xfs: reduce the number of pagb_lock roundtrips in xfs_alloc_clear_busy

2011-04-28T18:18:09+00:00

Instead of finding the per-ag and then taking and releasing the pagb_lock for every single busy extent completed sort the list of busy extents and only switch betweens AGs where nessecary. This becomes especially important with the online discard support which will hit this lock more often. Signed-off-by: Christoph Hellwig Signed-off-by: Alex Elder

xfs: kill support/debug.[ch]

2011-03-06T23:09:35+00:00

The remaining functionality in debug.[ch] is effectively just assert handling, conditional debug definitions and hex dumping. The hex dumping and assert function can be moved into the new printk module, while the rest can be moved into top-level header files. This allows fs/xfs/support/debug.[ch] to be completely removed from the codebase. Signed-off-by: Dave Chinner Reviewed-by: Alex Elder Reviewed-by: Christoph Hellwig

xfs: introduce new logging API.

2011-03-02T03:20:59+00:00

Most of the logging infrastructure in XFS is unneccessary and designed around the infrastructure supplied by Irix rather than Linux. To rationalise the logging interfaces, start by introducing simple printk wrappers similar to the dev_printk() infrastructure. Later patches will convert code to use this new interface.

xfs: use wait queues directly for the log wait queues

2010-12-21T01:09:01+00:00

The log grant queues are one of the few places left using sv_t constructs for waiting. Given we are touching this code, we should convert them to plain wait queues. While there, convert all the other sv_t users in the log code as well. Seeing as this removes the last users of the sv_t type, remove the header file defining the wrapper and the fragments that still reference it.

xfs: Extend project quotas to support 32bit project ids

2010-10-18T20:08:08+00:00

This patch adds support for 32bit project quota identifiers. On disk format is backward compatible with 16bit projid numbers. projid on disk is now kept in two 16bit values - di_projid_lo (which holds the same position as old 16bit projid value) and new di_projid_hi (takes existing padding) and converts from/to 32bit value on the fly. xfs_admin (for existing fs), mkfs.xfs (for new fs) needs to be used to enable PROJID32BIT support.

xfs: remove xfs_cred.h

2010-10-18T20:08:06+00:00

We're not actually passing around credentials inside XFS for a while now, so remove all xfs_cred.h with it's cred_t typedef and all instances of it. Signed-off-by: Christoph Hellwig Signed-off-by: Alex Elder

xfs: remove xfs_globals.h

2010-10-18T20:08:05+00:00

This header only provides one extern that isn't actually declared anywhere, and shadowed by a macro. Signed-off-by: Christoph Hellwig Signed-off-by: Alex Elder
