Subject: [PATCH v2 0/2] thread: add lock guard macros
Date: Mon, 16 Mar 2020 11:09:55 +0000 [thread overview]
Message-ID: <20200316110957.449700-1-stefanha@redhat.com> (raw)
Lock guards automatically call qemu_(rec_)mutex_unlock() when returning from a
function or leaving leaving a lexical scope. This simplifies code and
eliminates leaks (especially in error code paths).
This series adds lock guards for QemuMutex and QemuRecMutex. It does not
convert the entire tree but includes example conversions.

lockable: add lock guards
lockable: add QemuRecMutex support
