[PATCH -tip] remove the BKL: remove "BKL auto-drop" assumption from ext3_remount()
From: Alessio Igor Bogani
Date: Thu Apr 23 2009 - 09:16:45 EST
Fix ext3_remount()'s "schedule() drops the BKL automatically" assumption,
when ext3_mark_recovery_complete(), which can sleep, does not do that it can
lock up.
