Currently, online scrub reuses the xfs_readdir code to walk every entry in a directory. This isn't awesome for performance, since we end up cycling the directory ILOCK needlessly and coding around the particular quirks of the VFS dir_context interface. Create a streamlined version of readdir that keeps the ILOCK (since the walk function isn't going to copy stuff to userspace), skips a whole lot of directory walk cursor checks (since we start at 0 and walk to the end) and has a sane way to return error codes. Note: Porting the dotdot checking code is left for a subsequent patch. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Dave Chinner <dchinner@redhat.com>
