Mr. Ahmed,
The title "Changing executable page permissions with mmap causes
user-mode failures", I know you paraphrased one of Richard's
responses, but you picked up those pieces that don't convey the
complete, larger, picture. So, the better, more inclusive, and much
clearer title would be "Problems related to checking page crossing in
use_goto_tb()"
Yours,
Mr. Aleksandar
