From ea6749c705d9e629ed03c7336cc929fc6014b834 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Thu, 27 Dec 2012 22:21:58 -0800 Subject: Export __lockdep_no_validate__ Hack, but bcache needs a way around lockdep for locking during garbage collection - we need to keep multiple btree nodes locked for coalescing and rw_lock_nested() isn't really sufficient or appropriate here.
