xfs: replace xfs_sb_version checks with feature flag checks
Convert the xfs_sb_version_hasfoo() to checks against mp->m_features. Checks of the superblock itself during disk operations (e.g. in the read/write verifiers and the to/from disk formatters) are not converted - they operate purely on the superblock state. Everything else should use the mount features. Large parts of this conversion were done with sed with commands like this: for f in `git grep -l xfs_sb_version_has fs/xfs/*.c`; do sed -i -e 's/xfs_sb_version_has\(.*\)(&\(.*\)->m_sb)/xfs_has_\1(\2)/' $f done With manual cleanups for things like "xfs_has_extflgbit" and other little inconsistencies in naming. The result is ia lot less typing to check features and an XFS binary size reduced by a bit over 3kB: $ size -t fs/xfs/built-in.a text data bss dec hex filenam before 1130866 311352 484 1442702 16038e (TOTALS) after 1127727 311352 484 1439563 15f74b (TOTALS) Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.
