Adding the disk worked incorrectly with the new reload code. Fix it: - No operation should be performed on rdev marked as Candidate - After a metadata update operation, kick disk if role is 0xfffe else clear Candidate bit and continue with the regular change check. - Saving the mode of the lock resource to check if token lock is already locked, because it can be called twice while adding a disk. However, unlock_comm() must be called only once. - add_new_disk() is called by the node initiating the --add operation. If it needs to be canceled, call add_new_disk_cancel(). The operation is completed by md_update_sb() which will write and unlock the communication. Signed-off-by: Goldwyn Rodrigues <rgoldwyn@suse.com>
