Subject: xfs: Pull up xfs_attr_rmtval_invalidate
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d4034c4662af5d40de0655c641ddc6eccde0e8fc;p=linux.git

xfs: Pull up xfs_attr_rmtval_invalidate

This patch pulls xfs_attr_rmtval_invalidate out of
xfs_attr_rmtval_remove and into the calling functions.  Eventually
__xfs_attr_rmtval_remove will replace xfs_attr_rmtval_remove when we
introduce delayed attributes.  These functions are exepcted to return
-EAGAIN when they need a new transaction.  Because the invalidate does
not need a new transaction, we need to separate it from the rest of the
function that does.  This will enable __xfs_attr_rmtval_remove to
smoothly replace xfs_attr_rmtval_remove later.
