Subject: [PATCH 0/4] syscalls: remove compat_alloc_user_space callers
Date: Fri, 18 Sep 2020 15:24:35 +0200 [thread overview]
Message-ID: <20200918132439.1475479-1-arnd@arndb.de> (raw)
Going through compat_alloc_user_space() to convert indirect system call
arguments tends to add complexity compared to handling the native and
compat logic in the same code.
I have patches for all other uses of compat_alloc_user_space() as well,
and would expect that we can subsequently remove the interface itself.
