From: David Sterba Date: Wed, 24 May 2023 23:04:34 +0000 (+0200) Subject: btrfs: drop NOFAIL from set_extent_bit allocation masks X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7dde7a8ab32417f28c4ac0111f8a8389fc0501ff;p=linux.git btrfs: drop NOFAIL from set_extent_bit allocation masks The __GFP_NOFAIL passed to set_extent_bit first appeared in 2010 (commit f0486c68e4bd9a ("Btrfs: Introduce contexts for metadata reservation")), without any explanation why it would be needed. Meanwhile we've updated the semantics of set_extent_bit to handle failed allocations and do unlock, sleep and retry if needed. The use of the NOFAIL flag is also an outlier, we never want any of the set/clear extent bit helpers to fail, they're used for many critical changes like extent locking, besides the extent state bit changes.
