Description LiLinZhe 2015-12-07 13:57:19 UTC 
xfs_readdir will call  dir_emit. which receives type as parameter. it will always return DT_UNKNOWN.
Comment 1 Dave Chinner 2015-12-07 20:55:34 UTC 
Emitting DT_UNKOWN is expeceted behaviour if the filesystem does provide dirent type information to readdir. XFS filesystems that do not have the "mkfs.xfs -n ftype=1" parameter set will behave this way (have for 15 years). "ftype=1" is the default in recent xfsprogs releases so new filesystems will return types other than DT_UNKNOWN, but old/existing filesytsem without this parameter set will always return DT_UNKNOWN.

Not a bug, nothing needs fixing, please close.
