Subject: RFC: Changing daddr_t to 64 bits
Date: Sun, 25 Oct 2020 16:43:03 -0500 [thread overview]
Message-ID: <CAF9ehCWFnOuroehJcyMpA83v4+zXOZY0_ujcPpdds1MBKrVwJQ@mail.gmail.com> (raw)
Hi
The type daddr_t is defined to be long but per some IBM documentation, it
is "used for disk addresses, except in i-nodes on disk. The
*/usr/include/sys/filsys.h* file format describes the format of disk
addresses used in i-nodes."
RTEMS has this in our BSD derived code and 32-bits is too small for disk
addresses. We need it to be 64-bits at least for us.
Can I change it to be 64-bits for all targets?
Thanks.
