Subject: [PATCH v2 0/2] udf: Fix race between file type conversion and writeback
Date: Tue, 24 Mar 2026 11:53:11 +0100 [thread overview]
Message-ID: <20260324105132.30490-1-jack@suse.cz> (raw)
Hello,
here is a second version of patches to fix a race between conversion of UDF
file from inline format to the standard format and writeback resulting in
possible memory corruption. Review/Acks are welcome in particular for the
export of folio_prepare_writeback(). I'd like to push the fix to Linus soon as
it's kind of nasty issue.
Changes since v1:
* Fix crash in udf_writepages() when file had no folio in the mapping
