ceph: Fix incorrect flush end position calculation
[ Upstream commit f452a2204614fc10e2c3b85904c4bd300c2789dc ]
In ceph, in fill_fscrypt_truncate(), the end flush position is calculated
by:
loff_t lend = orig_pos + CEPH_FSCRYPT_BLOCK_SHIFT - 1;
but that's using the block shift not the block size.
Fix this to use the block size instead.
Fixes: 5c64737d2536 ("ceph: add truncate size handling support for fscrypt")
