Maybe we could store > that information in superblock and dump it during emergency thaw? Saving it in the superblock would require changing a bunch of file systems. What if we store this information in memory, and print it out under certain conditions (i.e., after a soft lockup detection, or upon request of some magic sysrq request)? Or we could create a tunable threshold and print a message after a file system has been frozen more than a particular specified duration, with that duration set conservatively to something like 60 or 120 seconds by default. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
