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).
V4:
-- do not use __GFP_NOMEMALLOC for zcomp private allocation. thanks
to Kyeongdon Kim for doing a good job testing and to Minchan Kim for
analysis.
V3,V2,V1: tweaking GFP flags, etc.
