2012-07-27dm thin metadata: remove pointless label from __commit_transactionJoe Thornber1-8/+7

2012-07-27dm persistent data: remove debug space map checkerJoe Thornber6-534/+11
Remove debug space map checker from dm persistent data. The space map checker is a wrapper for other space maps that double checks the reference counts are correct. It holds all these reference counts in memory rather than on disk, so uses a lot of memory and is thus restricted to small pools. As yet, this checker hasn't found any issues, but has caused a few of its own due to people turning it on by default with larger pools. Removing.

2012-07-27locks: prevent side-effects of locks_release_private before file_lock is ↵Filipe Brandenburger1-11/+6
initialized When calling fcntl(fd, F_SETLEASE, lck) [with lck=F_WRLCK or F_RDLCK], the custom signal or owner (if any were previously set using F_SETSIG or F_SETOWN fcntls) would be reset when F_SETLEASE was called for the second time on the same file descriptor. This bug is a regression of 2.6.37 and is described here: https://bugzilla.kernel.org/show_bug.cgi?id=43336 This patch reverts a commit from Oct 2004 (with subject "nfs4 lease: move the f_delown processing") which originally introduced the lm_release_private callback.

2012-07-27drm/exynos: add property for crtc modeJoonyoung Shim2-0/+73
This patch adds exynos specific property for crtc mode. The crtc mode property has tow modes - normal and blank. The normal mode is default mode and can use crtc normally. The blank mode turns off the private plane of crtc, so we don't see crtc screen but can see other plane screens.

2012-07-27powerpc/ftrace: Trace function graph entry before updating indexSteven Rostedt1-6/+5
As Colin Cross ported my x86 change to ARM, he also pointed out that powerpc is also behind in this fix. The commit 722b3c746953 "ftrace/graph: Trace function entry before updating index" fixes an issue with function graph tracing for x86, where if the called entry function decides not to trace interrupts, it can fail the check if an interrupt comes in just after the curr_ret_stack is updated. The solution is to call the entry function first, then update the curr_ret_stack if the entry function wants to be traced.
