Konstantin Belousov 8c2a54de80 Add kernel side support for BIO_DELETE/TRIM on UFS. ... The FS_TRIM fs flag indicates that administrator requested issuing of TRIM commands for the volume. UFS will only send the command to disk if the disk reports GEOM::candelete attribute. Since disk queue is reordered, data block is marked as free in the bitmap only after TRIM command completed. Due to need to sleep waiting for i/o to finish, TRIM bio_done routine schedules taskqueue to set the bitmap bit.
