From 2a86b3e74f12bcdd13ceb1bf333bc2d5f43b3c02 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 27 Feb 2013 17:04:49 -0800 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.
