Hi,
Just a comment:

+#define DEFINE_MUTEX(lock) \
+ mutex_t lock; \
+ SX_SYSINIT_FLAGS(lock, &(lock).sx, "lnxmtx", SX_NOWITNESS)
+
+static inline void
+linux_mutex_init(mutex_t *m)
+{
+
+ memset(&m->sx, 0, sizeof(m->sx));
+ sx_init_flags(&m->sx, "lnxmtx", SX_NOWITNESS);
+}
+
+#define mutex_init linux_mutex_init
I see you workaround the fact that Linux does not destroy any mutexes by
disabling witness. Do you have any plan to upgrade the Linux 3rd party code to
destroy mutexes?
