Yes, I missed has_dot_last_component completely.
As for the other checks:
dir.cc: 404: fh->error ():
* Done in unlink_nt
dir.cc: 409: fh->exists ():
* Done in _unlink_nt through NtOpenFile, which will return either
STATUS_OBJECT_NAME_NOT_FOUND or STATUS_OBJECT_PATH_NOT_FOUND,
both of which resolve to ENOENT
dir.cc: 413: isdev_dev (fh->dev ()):
* Done in unlink_nt
fhandler_siak_file.cc: 1842: if (!pc.isdir ())
* Done in _unlink_nt through NtOpenFile with flags FILE_DIRECTORY_FILE
and FILE_NON_DIRECTORY_FILE which will return STATUS_NOT_A_DIRECTORY
and STATUS_FILE_IS_A_DIRECTORY respectively.
Have I missed something else?
Also, I think it's better to have isdev_dev (fh->dev ()) return EROFS,
which is the same as unlink.
