Do not __GFP_ZERO allocated zcomp ->private pages. We keep allocated streams around and use them for read/write requests, so we supply a zeroed out ->private to compression algorithm as a scratch buffer only once -- the first time we use that stream. For the rest of IO requests served by this stream ->private usually contains some temporarily data from the previous requests. Signed-off-by:
