Subject: nilfs2: add setlease file operation
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f46bb13dc5d94471507ff9aed7a62a04d406b8b8;p=thirdparty%2Fkernel%2Flinux.git

nilfs2: add setlease file operation

Add the setlease file_operation to nilfs_file_operations and
nilfs_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.
