2013-05-07xfs: fallback to vmalloc for large buffers in xfs_compat_attrlist_by_handleEric Sandeen
Shamelessly copied from dchinner's: ad650f5b xfs: fallback to vmalloc for large buffers in xfs_attrmulti_attr_get xfsdump uses a large buffer for extended attributes, which has a kmalloc'd shadow buffer in the kernel. This can fail after the system has been running for some time as it is a high order allocation. Add a fallback to vmalloc so that it doesn't require contiguous memory and so won't randomly fail while xfsdump is running. This was done for xfs_attrlist_by_handle but xfs_compat_attrlist_by_handle (the 32-bit version) needs the same attention.

2012-07-31xfs: Convert to new freezing codeJan Kara
Generic code now blocks all writers from standard write paths. So we add blocking of all writers coming from ioctl (we get a protection of ioctl against racing remount read-only as a bonus) and convert xfs_file_aio_write() to a non-racy freeze protection. We also keep freeze protection on transaction start to block internal filesystem writes such as removal of preallocated blocks.

2012-05-14xfs: clean up xfs_bit.h includesDave Chinner
With the removal of xfs_rw.h and other changes over time, xfs_bit.h is being included in many files that don't actually need it. Clean up the includes as necessary. Also move the only-used-once xfs_ialloc_find_free() static inline function out of a header file that is widely included to reduce the number of needless dependencies on xfs_bit.h.

2012-05-14xfs: move xfsagino_t to xfs_types.hDave Chinner
Untangle the header file includes a bit by moving the definition of xfs_agino_t to xfs_types.h. This removes the dependency that xfs_ag.h has on xfs_inum.h, meaning we don't need to include xfs_inum.h everywhere we include xfs_ag.h.

2011-08-12xfs: remove subdirectoriesChristoph Hellwig
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/.
