From c6664b42c4e567792abdb17c958fb01c5bcfcb3a Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Thu, 12 Apr 2012 16:03:56 -0400 Subject: Btrfs: remove lock assert from get_restripe_target() This fixes a regression introduced by fc67c450. spin_is_locked() always returns 0 on UP kernels, which caused assert in get_restripe_target() to be fired on every call from btrfs_reduce_alloc_profile() on UP systems. Remove it completely for now, it's not clear if it's going to be needed in future.
