ubifs: Change gfp flags in page allocation for bulk read
In low memory situations, page allocations for bulk read can kill applications for reclaiming memory, and print an failure message when allocations are failed. Because bulk read is just an optimization, we don't have to do these and can stop page allocations. Though this siutation happens rarely, add __GFP_NORETRY to prevent from excessive memory reclaim and killing applications, and __GFP_WARN to suppress this failure message. For this, Use readahead_gfp_mask for gfp flags when allocating pages. Signed-off-by: Hyunchul Lee <cheol.lee@lge.com> Signed-off-by: Richard Weinberger <richard@nod.at>
