Subject: [PATCH 0/1] smb3: Memory leak/page refcount overflow fix
Date: Tue, 28 Feb 2023 22:38:37 +0000 [thread overview]
Message-ID: <20230228223838.3794807-1-dhowells@redhat.com> (raw)
Hi Steve,
Here's another fix patch for you. It fixes a leak of the pages extracted
for direct I/O. This was causing the page refcount to overflow and become
negative and then try_grab_page() would always fail on it.
I've pushed the patch here also:
