Subject: [PATCH v3 0/2] Syscall user redirection
Date: Sun, 12 Jul 2020 00:45:14 -0400 [thread overview]
Message-ID: <20200712044516.2347844-1-krisman@collabora.com> (raw)
Hi,
This is the v3 of the syscall user redirection patch, applying the
suggestions from Matthew and Kees. In particular, it modifies the ABI
to allow passing a range of allowed addresses and introduces kselftests
for the feature.
RFC/v1: https://lkml.org/lkml/2020/7/8/96
v2: https://lkml.org/lkml/2020/7/9/17
