The patch titled
Subject: idr: deprecate idr_remove_all()
has been removed from the -mm tree. Its filename was
idr-deprecate-idr_remove_all.patch
This patch was dropped because an updated version will be merged
------------------------------------------------------
From: Tejun Heo <tj@xxxxxxxxxx>
Subject: idr: deprecate idr_remove_all()
There was only one legitimate use of idr_remove_all() and a lot more
of incorrect uses (or lack of it). Now that idr_destroy() implies
idr_remove_all() and all the in-kernel users updated not to use it,
there's no reason to keep it around. Mark it deprecated so that we
can later unexport it.
idr_remove_all() is made an inline function calling __idr_remove_all()
to avoid triggering deprecated warning on EXPORT_SYMBOL().
