https://bugzilla.kernel.org/show_bug.cgi?id=211605 --- Comment #5 from CUI Hao (cuihao.leo@xxxxxxxxx) --- Sorry guys. I realized that I copy the wrong line of kernel message... I meant to say I got "attr2 mount option is deprecated" warning when "attr2" option is nowhere used... not "noattr2"... "noattr2" one is only triggered when I was doing more tests. More information about my mount command. I am using Arch Linux's stock one: $ mount -V mount from util-linux 2.36.1 (libmount 2.36.1: btrfs, namespaces, assert, debug) $ pacman -Q util-linux util-linux 2.36.1-4 -- You may reply to this email to add a comment.
