Hello.
In this patchset in the first patch I fixed module reference leak inside
blk-cgroup.c. In other patches I switched to a new put_getdisk() call,
which should be used if the disk was received by get_disk() or get_gendisk()
functions, which internally increase module reference.
The idea is to avoid confusion in the future and to have symmetric calls:
alloc_disk() -> put_disk() [as it is done in all the block drivers]
and
get_gendisk() -> put_gendisk() [if you need to find a disk by
minor,major]
The second sequence internally increases disk owner module reference on
get and decreases it on put.
Roman Pen (4):
block: fix module reference leak on put_disk() call for cgroups
throttle
block: introduce new call put_gendisk() in genhd.c
block,fs: switch to a new put_gendisk() call
hibernate: fix disk and module leak on successfull resume
