Subject: xfs: move xfs_rmap_update_defer_add to xfs_rmap_item.c
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=f449f70bf10ef204706a0df3d18dee5e0e229df1;p=users%2Fhch%2Fxfsprogs.git

xfs: move xfs_rmap_update_defer_add to xfs_rmap_item.c

Move the code that adds the incore xfs_rmap_update_item deferred work
data to a transaction live with the RUI log item code.  This means that
the rmap code no longer has to know about the inner workings of the RUI
log items.

As a consequence, we can get rid of the _{get,put}_group helpers.
