Subject: [PATCH 0/6] fs: deduplicate compat logic
Date: Mon, 11 Jan 2021 19:30:11 -0500 [thread overview]
Message-ID: <20210112003017.4010304-1-willemdebruijn.kernel@gmail.com> (raw)
From: Willem de Bruijn <willemb@google.com>
Use in_compat_syscall() to differentiate compat handling exactly
where needed, including in nested function calls. Then remove
duplicated code in callers.
Changes
RFC[1]->v1
- remove kselftest dependency on variant support in teardown
(patch is out for review, not available in linux-next/akpm yet)
- add patch 5: deduplicate set_user_sigmask compat handling
- add patch 6: deduplicate io_pgetevents sigmask compat handling
[1] RFC: https://github.com/wdebruij/linux-next-mirror/tree/select-compat-1
Willem de Bruijn (6):
selftests/filesystems: add initial select and poll selftest
select: deduplicate compat logic
ppoll: deduplicate compat logic
epoll: deduplicate compat logic
compat: add set_maybe_compat_user_sigmask helper
io_pgetevents: deduplicate compat logic
