namei: d_is_negative() should be checked before ->d_seq validation Fetching ->d_inode, verifying ->d_seq and finding d_is_negative() to be true does *not* mean that inode we'd fetched had been NULL - that holds only while ->d_seq is still unchanged. Shift d_is_negative() checks into lookup_fast() prior to ->d_seq verification.
