Theodore Ts'o 08e4a31243 ext4: validate the debug_want_extra_isize mount option at parse time 
commit 9803387c55f7d2ce69aa64340c5fdc6b3027dbc8 upstream.

Instead of setting s_want_extra_size and then making sure that it is a
valid value afterwards, validate the field before we set it.  This
avoids races and other problems when remounting the file system.
