Xiubo Li d9d00f71ab ceph: voluntarily drop Xx caps for requests those touch parent mtime ... For write requests the parent's mtime will be updated correspondingly. And if the 'Xx' caps is issued and when releasing other caps together with the write requests the MDS Locker will try to eval the xattr lock, which need to change the locker state excl --> sync and need to do Xx caps revocation. Just voluntarily dropping CEPH_CAP_XATTR_EXCL caps to avoid a cap revoke message, which could cause the mtime will be overwrote by stale one.
