70fcf68665 xfs: namespace the maximum length/refcount symbols
Actually namespace these variables properly, so that readers can tell
that this is an XFS symbol, and that it's for the refcount
functionality.

4d272929a5 xfs: rename metadata inode predicates
The predicate xfs_internal_inum tells us if an inumber refers to one of
the inodes rooted in the superblock.  Soon we're going to have internal
inodes in a metadata directory tree, so this helper should be renamed
to capture its limited scope.

Ondisk inodes will soon have a flag to indicate that they're metadata
inodes.  Head off some confusion by renaming the xfs_is_metadata_inode
predicate to xfs_is_internal_inode.

856a920ac2 xfs: add xfs_agbno_to_fsb and xfs_agbno_to_daddr helpers
Add helpers to convert an agbno to a daddr or fsbno based on a pag
structure.

This provides a simpler conversion and better type safety compared to the
existing code that passes the mount structure and the agno separately.

989d5ec317 xfs: report XFS_IS_CORRUPT errors to the health system
Whenever we encounter XFS_IS_CORRUPT failures, we should report that to
the health monitoring system for later reporting.

I started with this semantic patch and massaged everything until it
built:

@@
expression mp, test;
@@

- if (XFS_IS_CORRUPT(mp, test)) return -EFSCORRUPTED;
+ if (XFS_IS_CORRUPT(mp, test)) { xfs_btree_mark_sick(cur); return -EFSCORRUPTED; }

@@
expression mp, test;
identifier label, error;
@@

- if (XFS_IS_CORRUPT(mp, test)) { error = -EFSCORRUPTED; goto label; }
+ if (XFS_IS_CORRUPT(mp, test)) { xfs_btree_mark_sick(cur); error = -EFSCORRUPTED; goto label; }
