Linux 3.13 compat: Pass NULL for new delegated inode argument
|
|
|
|
This check was originally added for SLES10, a093c6a, to check for
|
|
a 'struct vfsmount *' argument which they added. However, since
|
|
SLES10 is based on a 2.6.16 kernel which is no longer supported
|
|
this functionality was dropped. The checks were refactored to
|
|
support Linux 3.13 without concern for historical versions.
