Subject: [PATCH v6 0/2] vfs: have syncfs() return error when there are writeback errors
Date: Thu, 16 Apr 2020 07:34:51 -0400 [thread overview]
Message-ID: <20200416113453.227229-1-jlayton@kernel.org> (raw)
v6:
- use READ_ONCE to ensure that compiler doesn't optimize away local var
The only difference from v5 is the change to use READ_ONCE to fetch the
bd_super pointer, to ensure that the compiler doesn't refetch it
afterward. Many thanks to Jan K. for the explanation!

vfs: track per-sb writeback errors and report them to syncfs
buffer: record blockdev write errors in super_block that it backs
