Subject[PATCH V3 0/4] zram: fix two races and one zram leak
Date
Hello,

Fixes three issues reported by Luis Chamberlain with one simpler approach:

- race between between zram_reset_device() and disksize_store() (1/4)

- zram leak during unloading module, which is one race between resetting
and removing device (2/4)

- race between zram_remove and disksize_store (3/4)

Also replace replace fsync_bdev with sync_blockdev since no one opens
it.(4/4)

V3:
- no code change
- update commit log or comment as Luis suggested
- add reviewed-by tag

V2:
- take another approach to avoid failing of zram_remove()
- add patch to address race between zram_reset_device() and
disksize_store()


Ming Lei (4):
zram: fix race between zram_reset_device() and disksize_store()
zram: don't fail to remove zram during unloading module
zram: avoid race between zram_remove and disksize_store
zram: replace fsync_bdev with sync_blockdev
