Subject: [PATCH 0/2] fs: copy_mount_options improvements
Date: Fri, 10 Jun 2016 13:11:23 -0700 [thread overview]
Message-ID: <cover.1465589343.git.luto@kernel.org> (raw)
Patch 1 fixes what is arguably a bug. I suspect it could cause
crashes or very large latency under unusual circumstanes. Since it
also deletes a bunch of code, I think it's a nice fix.
Patch 2 is an ABI change/fix. Any user code that would be affected
is currently buggy (i.e. results in incorrect option parsing), so I
suspect it can be applied safely.
Andy Lutomirski (2):
fs: Improve and simplify copy_mount_options
fs: Disallow mount options strings longer than PAGE_SIZE - 1
