Neaten cERROR and cFYI macros, reduce text space
~2.5K
Convert '__FILE__ ": " fmt' to '"%s: " fmt', __FILE__' to save text space
Surround macros with do {} while
Add parentheses to macros
Make statement expression macro from macro with assign
Remove now unnecessary parentheses from cFYI and cERROR uses

* Since cifs is a network file system, an "fsid" must be included for
|
|
* 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
