Subject: 32/64 bit b_rsector type
Date: Wed, 24 Mar 2004 14:36:29 +0800 [thread overview]
Message-ID: <40612C6D.6030205@shaolinmicro.com> (raw)
Dear all,
On a native 32-bit Linux system, the bh->b_resetor (type unsigned long)
max is limited to 16TB. For 64 bit systems, I know it can get through
this point, but what about if I chanage the bh->b_rsector in fs.h to u64
(unsigned long long on 32-bit systems)? Can I simply break through the
16TB on 32-bit Linux by doing so? Please advice with possiblility of
impacts. Thanks.
regards,
David Chow
