Subject: ext4: Print mount options in when mounting and add a remount message
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d4c402d9fd97a54bb7ed89f9e9869897eb4f6e1f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ext4: Print mount options in when mounting and add a remount message

This adds a "re-mounted" message to ext4_remount(), and both it and
the mount message in ext4_fill_super() now have the original mount
options data string.
