Subject: [PATCH v3 0/2] zram/zcomp: stream allocation fixes and tweaks

Hello,
	Two patches that address possible issues with compression
stream allocations under low memory or heavy fragmentation conditions.

These patches are considered to be a -stable material, however there
is no Cc -stable on "zram: try vmalloc() after kmalloc()" as of now.
We'd like to ask Kyeongdon to re-test and re-confirm (the patch has
been modified).

I split the patch set into separate threads. Two more patches
- zram: pass gfp from zcomp frontend to backend (Minchan Kim)
- zram/zcomp: do not zero out zcomp private pages (Sergey Senozhatsky)
(not a -stable material) will be posted separately.

Kyeongdon Kim (1):
  zram: try vmalloc() after kmalloc()

Sergey Senozhatsky (1):
  zram/zcomp: use GFP_NOIO to allocate streams
