Subject: [PATCH 0/9] ext4: Stop using ext4_writepage() for writeout of ordered data
Date: Wed, 30 Nov 2022 17:35:51 +0100 [thread overview]
Message-ID: <20221130162435.2324-1-jack@suse.cz> (raw)
Hello,
this patch series modifies ext4 so that we stop using ext4_writepage() for
writeout of ordered data during transaction commit (through
generic_writepages() from jbd2_journal_submit_inode_data_buffers()). Instead we
directly call ext4_writepages() from the
ext4_journal_submit_inode_data_buffers(). This is part of Christoph's effort
to get rid of the .writepage() callback in all filesystems.
Note that we still keep ext4_writepage() function for writeout of journalled
data. That can be also dealt with but let's untangle things one by one. Also
note that jbd2 still uses generic_writepages() in its
jbd2_journal_submit_inode_data_buffers() helper because it is still used from
OCFS2. Again, something to be dealt with in a separate patchset.
Patches pass for me tests on both 1k and 4k filesystems with dioreadlock and
without it.
Honza
