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)
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
