| Subject: f2fs: fix remount problem of option io_bits |
| |
| 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. |
