Subject: erofs: remove unnecessary output in erofs_show_options()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3dcb5fa23e16ef50b09e7a56b47d8e4c04ca09c0;p=linux.git

erofs: remove unnecessary output in erofs_show_options()

We have already handled cache_strategy option carefully,
so incorrect setting could not pass option parsing.
Meanwhile, print 'cache_strategy=(unknown)' can cause
failure on remount.
