2012-11-08xfs: add background scanning to clear eofblocks inodesBrian Foster1-0/+9
Create a new mount workqueue and delayed_work to enable background scanning and freeing of eofblocks inodes. The scanner kicks in once speculative preallocation occurs and stops requeueing itself when no eofblocks inodes exist. The scan interval is based on the new 'speculative_prealloc_lifetime' tunable (default to 5m). The background scanner performs unfiltered, best effort scans (which skips inodes under lock contention or with a dirty cache mapping).

2011-08-12xfs: remove subdirectoriesChristoph Hellwig1-0/+252
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/.
