Hu Weiwen b23b0cd57e ceph: don't truncate file in atomic_open ... commit 7cb9994754f8a36ae9e5ec4597c5c4c2d6c03832 upstream. Clear O_TRUNC from the flags sent in the MDS create request. `atomic_open' is called before permission check. We should not do any modification to the file here. The caller will do the truncation afterward.
