https://bugzilla.kernel.org/show_bug.cgi?id=76261 --- Comment #8 from kun.chen <kun.chen@xxxxxxxxxxxx> --- Sorry, I'm not say clear. Ext4 was mounted as dealloc, when applications write, they don't know shutdown happened later. So after emergency remount ro, flush worker begin write dirty data. This flow maybe normal. But as system already remounted to read only, whether we want or not, already can't flush dirty data back, so still writeback seems unnecessary. -- 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
