[01/10] xfs: relocate the eofb/cowb workqueue functions

Commit Message

Darrick J. Wong Jan. 18, 2021, 10:13 p.m. UTC

From: Darrick J. Wong <[e-mail]>

Move the xfs_{eof,cow}blocks_worker and xfs_queue_{eof,cow}blocks
functions further down in the file so that the cleanups in the next
patches won't have to pre-declare static functions.  No functional
changes.
