This series sanitizes the code around mount options and especially
improves consistency check on remount.
The "nilfs2: add barrier mount option" and "nilfs2: add nodiscard
mount option" add complementary mount options for existing "discard"
and "nobarrier" options. These allow user to re-enable or re-disable
non default options through remount.
The "nilfs2: use seq_puts to print mount options without argument"
replaces seq_printf uses in nilfs_show_options with simpler seq_puts
function.
The "nilfs2: pass remount flag to parse_options" adds a flag to the
argument of parse_options function and allows proper check of mount
options depending on the caller's context (i.e. new mount or remount).
Finally, the "nilfs2: get rid of nilfs_mount_options struct" is just a
cleanup which became possible by the previous change.
I will queue this series for linux next.
Thanks,
Ryusuke Konishi
