Subject: [PATCH 0/9] breakpoint: Rework arch validation
Date: Sun, 6 May 2018 21:19:46 +0200 [thread overview]
Message-ID: <1525634395-23380-1-git-send-email-frederic@kernel.org> (raw)
This is the first round of breakpoint code rework and cleanup. Here we
split up architecture validation and commit so that we don't mess up
with architecture internals in case attributes are rejected or slot
can't be reserved. It also unconfuse the code in general.

perf/breakpoint
HEAD: 0a788eff09988e58708c4a3ce7b8441ce3e7df95
Thanks,
Frederic
