Subject: [PATCH v2] direct-io: only inc/dec inode->i_dio_count for file systems
Date: Wed, 15 Apr 2015 16:01:35 -0600 [thread overview]
Message-ID: <1429135298-17153-1-git-send-email-axboe@fb.com> (raw)
Hi,
A proper patch series posting of the patch to skip inode dio counts
where we don't need them. Performance results and general notes in
patch #1. We can take this a bit further if we want to push this
truncate locking into the caller, but I'd like to keep that as a
separate patch series instead.
Changes since v2:
- Changed flag to DIO_SKIP_DIO_COUNT. Patch 2+3 will use this for
skipping the extra inc/dec for btrfs and ext4, so better rename it
to something that better tells what is happening in the deep mess
that is dio.
- Have inode_dio_inc/dec() helpers. Again, this better tells the caller
what is going on.
