Hello,
recently I found out that there was a bad bug in implementation of ioctl() FIOQSIZE
and so you dropped it from -ac patches (I wasn't probably at the time of bug discovery
on email and so after I returned I just read e-mails from l-k too briefly :(). I'm sending
you a patch against 2.7.1-ac1 which should again add support for FIOQSIZE and without
that nasty bug (appropriate copy_to_user() added).
