Subject: bio bounce buffering fixes
Date: Tue, 14 Jul 2026 15:11:57 +0200	[thread overview]
Message-ID: <20260714131318.2670042-1-hch@lst.de> (raw)

Hi all,

this series fixes a few issues with the bio bounce buffering code.

The patches are on top of the "block: validate direct I/O memory
alignment" series from Keith.

A git tree with that already applied is available here for convenience:
