Current _ext4_show_options() do not distinguish MOPT_2 flag, so it mixed
extend sbi->s_mount_opt2 options with sbi->s_mount_opt, it could lead to
show incorrect options, e.g. show fc_debug_force if we mount with
errors=continue mode and miss it if we set.
$ mkfs.ext4 /dev/pmem0
$ mount -o errors=remount-ro /dev/pmem0 /mnt
$ cat /proc/fs/ext4/pmem0/options | grep fc_debug_force
#empty
$ mount -o remount,errors=continue /mnt
$ cat /proc/fs/ext4/pmem0/options | grep fc_debug_force
fc_debug_force
$ mount -o remount,errors=remount-ro,fc_debug_force /mnt
$ cat /proc/fs/ext4/pmem0/options | grep fc_debug_force
#empty

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
