Theodore Ts'o e40ff21389 ext4: force revalidation of directory pointer after seekdir(2) 
A malicious user could force the directory pointer to be in an invalid
spot by using seekdir(2).  Use the mechanism we already have to notice
if the directory has changed since the last time we called
ext4_readdir() to force a revalidation of the pointer.
