Can you check below commit? It looks w/o it we may lose default option after
remount.

Hi Chao,
It looks like there was a bug in remount at that time, but I think the
fix above is not correct.
from the patch '498c5e9fcd10', I think it was caused by clearing
sbi->mount_opt.opt before
parsing. I think remount should not change the options which were
specified by user in
previous mount unless user specifies in remount.
Thanks,
Chengguang
