Subject: [PATCH] ramfs: fix mount source show for ramfs
Date: Wed, 11 Aug 2021 20:28:11 +0800	[thread overview]
Message-ID: <20210811122811.2288041-1-yangerkun@huawei.com> (raw)

ramfs_parse_param does not parse key "source", and will convert
-ENOPARAM to 0. This will skip vfs_parse_fs_param_source in
vfs_parse_fs_param, which lead always "none" mount source for ramfs. Fix
it by parse "source" in ramfs_parse_param.
