J. Bruce Fields b2c0cea6b1 nfsd4: check for negative dentry before use in nfsv4 readdir ... After 2f9092e102 "Fix i_mutex vs. readdir handling in nfsd" (and 14f7dd63 "Copy XFS readdir hack into nfsd code"), an entry may be removed between the first mutex_unlock and the second mutex_lock. In this case, lookup_one_len() will return a negative dentry. Check for this case to avoid a NULL dereference. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Reviewed-by: J. R.
