From: Xiubo Li <xiubli@xxxxxxxxxx>
The fscrypt code will use i_blkbits to setup the 'ci_data_unit_bits'
when allocating the new inode, but ceph will initiate i_blkbits
ater when filling the inode, which is too late. Since the
'ci_data_unit_bits' will only be used by the fscrypt framework so
initiating i_blkbits with CEPH_FSCRYPT_BLOCK_SHIFT is safe.
Fixes: commit 5b1188847180 ("fscrypt: support crypto data unit size
less than filesystem block size")
