[RFC PATCH v1 0/8] small bugfixes and code improvements for zram

[Jiang Liu]

This patchset is to fix issues in zram found by code inspection.
There is still one more issue left: should we repalce zram_stat64_xxx()
with atomic64_xxx()?

Jiang Liu (8):
  zram: simplify and optimize zram_to_dev()
  zram: avoid invalid memory access in zram_exit()
  zram: use zram->lock to protect zram_free_page() in swap free notify
    path
  zram: destroy all devices on error recovery path in zram_init()
  zram: avoid double free in error recovery path of zram_bvec_write()
  zram: avoid access beyond the zram device
  zram: optimize memory operations with clear_page()/copy_page()
  zram: protect sysfs handler from invalid memory access
