[PATCH] Fix suspend with traced tasks

2006-03-31T20:18:50+00:00

strace /bin/bash misbehaves after resume; this fixes it.

(akpm: it's scary calling refrigerator() in state TASK_TRACED, but it seems to
do the right thing).

[PATCH] swsusp: freeze user space processes first

2006-03-23T15:38:08+00:00

Allow swsusp to freeze processes successfully under heavy load by freezing
userspace processes before kernel threads.

[Thanks to Nigel Cunningham  for suggesting the
way to go.]

[PATCH] swsusp: documentation updates

2006-03-23T15:38:07+00:00

Update suspend-to-RAM documentation with new machines, and makes message
when processes can't be stopped little clearer.  (In one case, waiting
longer actually did help).

From: "Rafael J. Wysocki" 

  Warn in the documentation that data may be lost if there are some
  filesystems mounted from USB devices before suspend.

  [Thanks to Alan Stern for providing the answer to the question in the
  Q:-A: part.]

[PATCH] pm: fix process freezing

2005-09-05T07:06:17+00:00

If process freezing fails, some processes are frozen, and rest are left in
"were asked to be frozen" state.  Thats wrong, we should leave it in some
consistent state.

[PATCH] remove busywait in refrigerator

2005-09-05T07:06:14+00:00

This should make refrigerator sleep properly, not busywait after the first
schedule() returns.

[PATCH] pm: clean up process.c

2005-07-08T01:23:43+00:00

freezeable() already tests for TRACED/STOPPED processes, no need to do it
twice.

[PATCH] Cleanup patch for process freezing

2005-06-26T00:10:13+00:00

1. Establish a simple API for process freezing defined in linux/include/sched.h:

   frozen(process)		Check for frozen process
   freezing(process)		Check if a process is being frozen
   freeze(process)		Tell a process to freeze (go to refrigerator)
   thaw_process(process)	Restart process
   frozen_process(process)	Process is frozen now

2. Remove all references to PF_FREEZE and PF_FROZEN from all
   kernel sources except sched.h

3. Fix numerous locations where try_to_freeze is manually done by a driver

4. Remove the argument that is no longer necessary from two function calls.

5. Some whitespace cleanup

6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
   cleared before setting PF_FROZEN, recalc_sigpending does not check
   PF_FROZEN).

This patch does not address the problem of freeze_processes() violating the rule
that a task may only modify its own flags by setting PF_FREEZE. This is not clean
in an SMP environment. freeze(process) is therefore not SMP safe!

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
