2015-02-23xfs: remove xfs_mod_incore_sb APIDave Chinner
Now that there are no users of the bitfield based incore superblock modification API, just remove the whole damn lot of it, including all the bitfield definitions. This finally removes a lot of cruft that has been around for a long time. Credit goes to Christoph Hellwig for providing a great patch connecting all the dots to enale us to do this. This patch is derived from that work. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>

2015-01-22xfs: sanitise sb_bad_features2 handlingDave Chinner
We currently have to ensure that every time we update sb_features2 that we update sb_bad_features2. Now that we log and format the superblock in it's entirety we actually don't have to care because we can simply update the sb_bad_features2 when we format it into the buffer. This removes the need for anything but the mount and superblock formatting code to care about sb_bad_features2, and hence removes the possibility that we forget to update bad_features2 when necessary in the future.

2014-12-24xfs: Keep sb_bad_features2 consistent with sb_features2Jan Kara
Currently when we modify sb_features2, we store the same value also in sb_bad_features2. However in most places we forget to mark field sb_bad_features2 for logging and thus it can happen that a change to it is lost. This results in an inconsistent sb_features2 and sb_bad_features2 fields e.g. after xfstests test xfs/187. Fix the problem by changing XFS_SB_FEATURES2 to actually mean both sb_features2 and sb_bad_features2 fields since this is always what we want to log. This isn't ideal because the fact that XFS_SB_FEATURES2 means two fields could cause some problem in future however the code is hopefully less error prone that it is now.

More consolidatation for the on-disk format defintions. Note that the XFS_IS_REALTIME_INODE moves to xfs_linux.h instead as it is not related to the on disk format, but depends on a CONFIG_ option.

2014-07-30xfs: require 64-bit sector_tChristoph Hellwig
Trying to support tiny disks only and saving a bit memory might have made sense on an SGI O2 15 years ago, but is pretty pointless today. Remove the rarely tested codepath that uses various smaller in-memory types to reduce our test matrix and make the codebase a little bit smaller and less complicated.
