I see that these messages have been introduced with f8b92ba67c5d ("mount: Add mount warning for impending timestamp expiry") resp. 0ecee6699064 ("fix use-after-free of mount in mnt_warn_timestamp_expiry()") and I was wondering if there is any chance to either adjust this to pr_debug (but then it would still show up in dmesg, right?) or to only warn once when it's mounted, but not on re-mount? Thanks, Christian. -- BOFH excuse #83: Support staff hung over, send aspirin and come back LATER.
