Subject: affs: add setlease file operation
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=663cdef61a27bf593e48cedc37f28ed5cfbf8c11;p=thirdparty%2Fkernel%2Flinux.git

affs: add setlease file operation

Add the setlease file_operation to affs_file_operations and
affs_dir_operations, pointing to generic_setlease.  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.
