Subject: [dm-devel] [PATCH v2 00/19] bio: check return values of bio_add_page
Date: Thu, 30 Mar 2023 03:43:42 -0700 [thread overview]
Message-ID: <cover.1680172791.git.johannes.thumshirn@wdc.com> (raw)
We have two functions for adding a page to a bio, __bio_add_page() which is
used to add a single page to a freshly created bio and bio_add_page() which is
used to add a page to an existing bio.
While __bio_add_page() is expected to succeed, bio_add_page() can fail.
This series converts the callers of bio_add_page() which can easily use
__bio_add_page() to using it and checks the return of bio_add_page() for
callers that don't work on a freshly created bio.
Lastly it marks bio_add_page() as __must_check so we don't have to go again
and audit all callers.
Changes to v1:
- Removed pointless comment pointed out by Willy
- Changed commit messages pointed out by Damien
- Colledted Damien's Reviews and Acks
