Subject: fix swap on NFS
Date: Fri, 14 Jun 2024 12:03:24 +0200	[thread overview]
Message-ID: <20240614100329.1203579-1-hch@lst.de> (raw)

Hi all,

as of 6.10-rc swap can swap out larger than PAGE_SIZE chunks, which
trips a VM_BUG_ON in NFS.  This trivial patch seems to fix it to me,
but I haven't really figured out what Fixes tag this should get.

Also cifs has the same VM_BUG_ON and will also need a similar fix, but
I'll leave it to people with a working test setup.
