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.
Kyeongdon Kim (1): zram: try vmalloc() after kmalloc()
Sergey Senozhatsky (1): zram/zcomp: use GFP_NOIO to allocate streams
