Subject: [PATCH 0/2] min_t type casting bug fixes
Date: Fri, 11 Mar 2016 14:21:56 +0800 [thread overview]
Message-ID: <20160311062156.131015797@redhat.com> (raw)
Hi,
We found a min_t type casting issue in fs/proc/vmcore.c, it uses smaller
type in min_t so that during i386 PAE testing 64bit value was trucated
and then cause saving vmcore failure and BUG() for mmap case.
I introduced new macros min_lt and max_lt to select the larger data type
in x and y. Then use it in 2nd patch.
Any comments are appreciated.
Thanks
Dave
