Peter Zijlstra 53d472f972 lockdep/mm: Fix might_fault() lockdep check of current->mm->mmap_lock ... [ Upstream commit a1b65f3f7c6f7f0a08a7dba8be458c6415236487 ] Turns out that this commit, about 10 years ago: 9ec23531fd ("sched/preempt, mm/fault: Trigger might_sleep() in might_fault() with disabled pagefaults") ... accidentally (and unnessecarily) put the lockdep part of __might_fault() under CONFIG_DEBUG_ATOMIC_SLEEP=y. This is potentially notable because large distributions such as Ubuntu are running with !CONFIG_DEBUG_ATOMIC_SLEEP. Restore the debug check. [ mingo: Update changelog. ] Fixes: 9ec23531fd ("sched/preempt, mm/fault: Trigger might_sleep() in might_fault() with disabled pagefaults") Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Andrew Morton <akpm@linux-foundation.org> Link: https://lore.kernel.org/r/20241104135517.536628371@infradead.org Signed-off-by: Sasha Levin <sashal@kernel.org>		2025-04-10 14:33:30 +02:00
