We're currently support two paths from VFS to preallocate unwritten extents(from FS_IOC_RESVSP, or fallocate()), likewise, behavior of punching-hole should be treated as the same, this patch tries to teach file_ioctl() to handle FS_IOC_UNRESVSP, underlying filesystem like ocfs2 is wise enough to do the rest of work;-) Signed-off-by: Tristan Ye <tristan.ye at oracle.com> --- fs/ioctl.c

Hello, the following patch series implements quotas for OCFS2. The patch series is based on: git://git.kernel.org/pub/scm/linux/kernel/git/mfasheh/ocfs2.git linux-next I've adressed Joel's comments, also node recovery is now fully working and I've fixed a few issues I found during my testing. So I'm currently not aware of any bugs. Please review, test, comment. Thanks.

The following series of patches attempts to detach metadata I/O from struct inode. They are currently tied together pretty tightly. Metadata reads happen via the ocfs2_read_blocks() functions, writes via both jbd2 and ocfs2_write_blocks(). - Each inode has a cache of associated metadata blocks stored on its ip_metadata_cache member. The ocfs2_read/write_blocks() functions take a struct
