PM / Hibernate: Swap, use KERN_CONT

2009-12-06T15:16:24+00:00

Use KERN_CONT in save_image() for printks, so that anybody won't
try to add a loglevel.

PM / Hibernate: Move swap functions to kernel/power/swap.c.

2009-12-06T15:15:53+00:00

Move hibernation code's functions for allocating and freeing swap
from swsusp.c to swap.c, which is where you'd expect to find them.

PM / Hibernate: Fix error handling in save_image()

2009-11-03T10:02:43+00:00

There are too many retval variables in save_image(). Thus error return
value from snapshot_read_next() may be ignored and only part of the
snapshot (successfully) written.

Remove 'error' variable, invert the condition in the do-while loop
and convert the loop to use only 'ret' variable.

Switch the rest of the function to consider only 'ret'.

Also make sure we end printed line by \n if an error occurs.

PM / Hibernate: Fix blkdev refleaks

2009-11-03T10:01:46+00:00

While cruising through the swsusp code I found few blkdev reference
leaks of resume_bdev.

swsusp_read: remove blkdev_put altogether. Some fail paths do
             not do that.
swsusp_check: make sure we always put a reference on fail paths
software_resume: all fail paths between swsusp_check and swsusp_read
                 omit swsusp_close. Add it in those cases. And since
                 swsusp_read doesn't drop the reference anymore, do
                 it here unconditionally.

[rjw: Fixed a small coding style issue.]

headers: utsname.h redux

2009-09-24T01:13:10+00:00

* remove asm/atomic.h inclusion from linux/utsname.h --
   not needed after kref conversion
 * remove linux/utsname.h inclusion from files which do not need it

NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however
due to some personality stuff it _is_ needed -- cowardly leave ELF-related
headers and files alone.

block: fix bad definition of BIO_RW_SYNC

2009-02-18T09:32:00+00:00

We can't OR shift values, so get rid of BIO_RW_SYNC and use BIO_RW_SYNCIO
and BIO_RW_UNPLUG explicitly. This brings back the behaviour from before

[PATCH] kill obsolete temporary comment in swsusp_close()

2008-12-04T09:22:54+00:00

it had been put there to mark the call of blkdev_put() that
needed proper argument propagated to it; later patch in the
same series had done just that.
