ocfs2: Initialize data_ac (might be used uninitialized)
CLANG found that there is a path that has data_ac uninitialized,
this place
2917 /* This gets us the dx_root */
2918 ret = ocfs2_reserve_new_metadata_blocks(osb, 1, &meta_ac);
2919 if (ret) {
3
Taking true branch
2920 mlog_errno(ret);
2921 goto out;
4
Control jumps to line 3168
2922 }
Goes to the out: label without data_ac being initialized.
Ciao, Marcus
