The patch titled
Subject: dlm: convert to idr_alloc()
has been removed from the -mm tree. Its filename was
dlm-convert-to-idr_alloc.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Tejun Heo <tj@xxxxxxxxxx>
Subject: dlm: convert to idr_alloc()
Convert to the much saner new idr interface. Error return values from
recover_idr_add() mix -1 and -errno. The conversion doesn't change
that but it looks iffy.
