      Revert "mm: simplify code of swap.c" · 83896fb5
      Linus Torvalds authored 
      This reverts commit d8505dee.

Chris Mason ended up chasing down some page allocation errors and pages
stuck waiting on the IO scheduler, and was able to narrow it down to two
commits: commit 744ed144 ("mm: batch activate_page() to reduce lock
contention") and d8505dee ("mm: simplify code of swap.c").

This reverts the second one.

      xfs: Do not name variables "panic" · cf78859f
      Geert Uytterhoeven authored 
      On platforms that call panic() inside their BUG() macro (m68k/sun3, and
all platforms that don't set HAVE_ARCH_BUG), compilation fails with:

| fs/xfs/support/debug.c: In function ‘xfs_cmn_err’:
| fs/xfs/support/debug.c:92: error: called object ‘panic’ is not a function

as the local variable "panic" conflicts with the "panic()" function.
Rename the local variable to resolve this.

      perf tools: Fix tracepoint id to string perf.data header table · ad7f4e3f
      Arnaldo Carvalho de Melo authored 
      It was broken by f006d25a that passed just the event name, not the complete
sys:event that it expected to open the /sys/.../sys/sys:event/id file to get
the id.

Fix it by moving it to after parse_events in cmd_record, as at that point
we can just traverse the evsel_list and use evsel->attr.config +
event_name(evsel) instead of re-opening the /id file.

      Btrfs: forced readonly mounts on errors · acce952b
      liubo authored 
      This patch comes from "Forced readonly mounts on errors" ideas.

As we know, this is the first step in being more fault tolerant of disk
corruptions instead of just using BUG() statements.

The major content:
- add a framework for generating errors that should result in filesystems
  going readonly.
- keep FS state in disk super block.
- make sure that all of resource will be freed and released at umount time.
- make sure that fter FS is forced readonly on error, there will be no more
  disk change before FS is corrected. For this, we should stop write operation.

After this patch is applied, the conversion from BUG() to such a framework can
happen incrementally.
