Hi, this patch seems still leave in linux-next, should we pull it to
mainline?
在 2021/8/11 20:28, yangerkun 写道:
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.
