Caller 0xffffffffa025486e Same problem Cai Qian just reported - a remote symlink with a bmbt verifier attached to it. > I can reproduce it every time with xfstest 013 on 3.8.0-rc5. And the configuration you are testing? I'd suggest that you add an: ASSERT(bp->b_ops == NULL); into xfs_symlink() after the xfs_trans_get_buf() call in the remote symlink crate loop, because the problem occurring implies that the code is getting a new buffer with a stale ops structure on it (though I can't see how that is possible right now). You should probably put the same assert into xfs_inactive_symlink_rmt() between the get buf and the xfs_trans_binval() call, and into xfs_readlink_bmap() after the contents of a symlink are read from disk.
