Subject: 2.6.23-rc7-mm1: r/o mounts joke with lockdep
Date: Mon, 24 Sep 2007 13:51:05 +0400 [thread overview]
Message-ID: <20070924095105.GD6757@localhost.sw.ru> (raw)
static void lock_and_coalesce_cpu_mnt_writer_counts(void)
{
int cpu;
struct mnt_writer *cpu_writer;
for_each_possible_cpu(cpu) {
cpu_writer = &per_cpu(mnt_writers, cpu);
spin_lock_nested(&cpu_writer->lock, 42);
^^^^
What the heck is going on? Given that MAX_LOCKDEP_SUBCLASSES is only 8,
this reliably turns off lockdep at boot.
