Subject: test/client: When testing large io, consider fscrypt
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=be99ab3e33df4d33db7b96d0d52a27eba87b4507;p=ceph.git

test/client: When testing large io, consider fscrypt

When testing large io sizes and clamping that io, consider
fscrypt max io size. This max io size should be a multiple
of 4K (fscrypt block size), but not to exceed INT_MAX.
