X-Git-Tag: rel_imx_5.10.35_2.0.0-somdevices.0~977^2~29
X-Git-Url: https://git.somdevices.com/?a=commitdiff_plain;h=69c0dd29f75292cf90f032365e0f9d96b7ded5ca;p=linux.git

f2fs: ignore compress mount option on image w/o compression feature

to keep consistent with behavior when passing compress mount option
to kernel w/o compression feature, so that mount may not fail on
such condition.
