Subject: [PATCH v2 0/2] maple_tree: mas_wr_append() fix ups
Date: Fri, 18 Aug 2023 20:43:54 -0400 [thread overview]
Message-ID: <20230819004356.1454718-1-Liam.Howlett@oracle.com> (raw)
There is a potential of an update causing issue with a reader when
appending, so disable the append operation when readers a present.
The code was also missing some documentation, tracing, and some cleanup
was possible. These changes are in the second patch as there's no
compelling reason to require a difficult backport.
Changes since v1:
- Added fixes tag to the first patch
v1: https://lore.kernel.org/linux-mm/20230817191505.1170876-1-Liam.Howlett@oracle.com/
