Subject[PATCH AUTOSEL 4.19 128/191] f2fs: fix remount problem of option io_bits
Date
From: Chengguang Xu <cgxu519@gmx.com>

[ Upstream commit c6b1867b1da3b1203b4c49988afeebdcbdf65499 ]

Currently we show mount option "io_bits=%u" as "io_size=%uKB",
it will cause option parsing problem(unrecognized mount option)
in remount.
