Subject: xfs: drop dmapi hooks
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=288699fecaffa1ef8f75f92020cbb593a772e487;p=linux.git

xfs: drop dmapi hooks

Dmapi support was never merged upstream, but we still have a lot of hooks
bloating XFS for it, all over the fast pathes of the filesystem.

This patch drops over 700 lines of dmapi overhead.  If we'll ever get HSM
support in mainline at least the namespace events can be done much saner
in the VFS instead of the individual filesystem, so it's not like this
is much help for future work.
