https://bugzilla.kernel.org/show_bug.cgi?id=62751 Jan Kara <jack@xxxxxxx> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jack@xxxxxxx --- Comment #3 from Jan Kara <jack@xxxxxxx> --- Thanks. This looks like a problem in the shrinker for ext4 extent cache. Apparently we burn too much time (the longest stall is over 2 seconds) searching and freeing extents without giving CPU a break. Ideally we should make the shrinker more efficient (since I don't believe it was called with so many entries to free) but if that won't work out easily, we should at least sprinkle some cond_resched() into the shrinker code as a band aid. I'll see what we can do. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
