Subject: xfs: add setlease file operation
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6163b5da2f5eff5fdad6bad9fa1ca37c7d2d0d5d;p=thirdparty%2Fkernel%2Flinux.git

xfs: add setlease file operation

Add the setlease file_operation pointing to generic_setlease to the xfs
file_operations structures. A future patch will change the default
behavior to reject lease attempts with -EINVAL when there is no
setlease file operation defined. Add generic_setlease to retain the
ability to set leases on this filesystem.
