Subject: [Bug 201685] ext4 file system corruption
Date: Fri, 30 Nov 2018 18:05:45 +0000 [thread overview]
Message-ID: <bug-201685-13602-GWTT9BkV13@https.bugzilla.kernel.org/> (raw)

--- Comment #94 from Jens Axboe (axboe@kernel.dk) ---
In terms of ext4 changes, it'd be interesting to just revert this one:
commit ac22b46a0b65dbeccbf4d458db95687e825bde90
Author: Jens Axboe <axboe@kernel.dk>
Date: Fri Aug 17 15:45:42 2018 -0700
ext4: readpages() should submit IO as read-ahead
as that guy is generally just not trust worthy. In all seriousness, though, it
shouldn't cause issues (or I would not have done it), and we already do this
for readpages in general, but I guess we could have an older bug in ext4 that
depends deeply on read-ahead NOT failing. Not sure how likely that is, Ted can
probably comment on that.
But it's a trivial revert, and it could potentially be implicated.
