Re: [libvirt PATCH v5 2/9] virthread: Introduce virLockGuard

Locks a virMutex on creation and unlocks it in its destructor. The VIR_LOCK_GUARD macro is used instead of "g_auto(virLockGuard)" to work around a clang issue (see https://bugs.llvm.org/show_bug.cgi?id=3888 and https://bugs.llvm.org/show_bug.cgi?id=43482). Typical usage: void function(virMutex *m) { VIR_LOCK_GUARD lock = virLockGuardLock(m); /* `m` is locked, and released automatically on scope exit */ ... while (expression) { VIR_LOCK_GUARD lock2 = virLockGuardLock(...); /* similar */ } } Signed-off-by: Tim Wiederhake <twiederh(a)redhat.com&gt; --- src/libvirt_private.syms | 2 ++ src/util/virthread.c | 15 +++++++++++++++ src/util/virthread.h | 10 ++++++++++ 3 files changed, 27 insertions(+)
