checkpatch complains about source files with filenames (e.g. in these cases just below the SPDX header in comments at the top of various files in fs/cifs). It also is helpful to change this now so will be less confusing when the parent directory is renamed e.g. from fs/cifs to fs/smb_client (or fs/smbfs) Reviewed-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com>

|
|
* any nfs exports file entries which refer to cifs paths. In addition
|
|
* the cifs mount must be mounted with the "serverino" option (ie use stable
|
|
* server inode numbers instead of locally generated temporary ones).
|
|
* Although cifs inodes do not use generation numbers (have generation number
|
|
* of zero) - the inode number alone should be good enough for simple cases
|
|
* in which users want to export cifs shares with NFS. The decode and encode
|
|
* could be improved by using a new routine which expects 64 bit inode numbers
|
|
* instead of the default 32 bit routines in fs/exportfs
