2011-10-11xfs: move more delwri setup into xfs_buf_delwri_queueChristoph Hellwig
Do not transfer a reference held by the caller to the buffer on the list, or decrement it in xfs_buf_delwri_queue, but instead grab a new reference if needed, and let the caller drop its own reference. Also move setting of the XBF_DELWRI and XBF_ASYNC flags into xfs_buf_delwri_queue, and only do it if needed. Note that for now xfs_buf_unlock already has XBF_DELWRI, but that will change in the following patches.

2011-10-11xfs: remove the unlock argument to xfs_buf_delwri_queueChristoph Hellwig
We can just unlock the buffer in the caller, and the decrement of b_hold would also be needed in the !unlock, we just never hit that case currently given that the caller handles that case.

2011-10-11xfs: remove delwri buffer handling from xfs_buf_iorequestChristoph Hellwig
We cannot ever reach xfs_buf_iorequest for a buffer with XBF_DELWRI set, given that all write handlers make sure that the buffer is remove from the delwri queue before, and we never do reads with the XBF_DELWRI flag set (which the code would not handle correctly anyway).

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/.
