Subject: [f2fs-dev] Fix inode sem regression for nowait
Date: Wed, 11 Sep 2019 11:45:14 -0500
Message-ID: <20190911164517.16130-1-rgoldwyn@suse.de> (raw)
In-Reply-To: <20190911093926.pfkkx25mffzeuo32@alap3.anarazel.de>

This changes the way we acquire the inode semaphore when
the I/O is marked with IOCB_NOWAIT. The regression was discovered
in AIM7 and later by Andres in ext4. This has been fixed in
XFS by 942491c9e6d6 ("xfs: fix AIM7 regression")

I realized f2fs and btrfs also have the same code and need to
be updated.

Regards,
