fuse-bridge: update to protocol minor version 22
7.17 - Distinguishes between POSIX and BSD locking support via a separate BSD locking support init flag. Older protocol versions (since BSD support was added) export both types of locking requests if FUSE_POSIX_LOCKS is specified. Gluster sets this flag, so set FUSE_FLOCK_LOCKS as well on kernels that support version 17 or newer. 7.18 - Adds ioctl() support for directories (and the associated FUSE_IOCTL_DIR flag). Gluster does not support the ioctl request, so no changes are required. Update the header. - Adds support for the delete notification to allow a filesystem to inform the kernel of a deleted inode. No gluster changes required. 7.19 - Adds support for the fallocate request. Gluster already supports fallocate and includes the request opcode definition and data structure. Update the header version number. 7.20 - Adds the FUSE_AUTO_INVAL_DATA init flag to enable attribute updates on reads and automatic cache invalidation on mtime changes. Behavior does not change unless the init flag is specified, no gluster changes required. Update header. 7.21 - Adds readdirplus support and updates the poll request to include events. Gluster already supports readdirplus and includes the relevant data structures. Poll is not supported, so no changes are required. Update the header with some missing READDIRPLUS_AUTO bits. 7.22 - Adds real asynchronous direct I/O support. Gluster already supports/enables the associated bit (FUSE_ASYNC_DIO), no further changes are required. Update the header.
