Subject: [PATCH] Fix preadv, pwritev and fallocate for -D_FILE_OFFSET_BITS=64
Date: Wed, 04 Nov 2009 21:59:00 -0000 [thread overview]
Message-ID: <20091104215904.GJ3047@sunsite.ms.mff.cuni.cz> (raw)
Hi!
As reported in http://bugzilla.redhat.com/533063 , preadv/pwritev prototypes
are wrong on 32-bit arches with -D_FILE_OFFSET_BITS=64 and as I've just
found, fallocate is wrong too.
The problem is that only off_t is remapped to the 64-bit type transparently,
__off_t is not.
Fixed thusly.

* misc/sys/uio.h (preadv, pwritev): Fix type of last argument
when -D_FILE_OFFSET_BITS=64.
* sysdeps/unix/sysv/linux/ia64/bits/fcntl.h (fallocate): Fix types
of last two arguments when -D_FILE_OFFSET_BITS=64.
* sysdeps/unix/sysv/linux/i386/bits/fcntl.h (fallocate): Likewise.
* sysdeps/unix/sysv/linux/s390/bits/fcntl.h (fallocate): Likewise.
* sysdeps/unix/sysv/linux/powerpc/bits/fcntl.h (fallocate): Likewise.
* sysdeps/unix/sysv/linux/x86_64/bits/fcntl.h (fallocate): Likewise.
* sysdeps/unix/sysv/linux/sparc/bits/fcntl.h (fallocate): Likewise.
* sysdeps/unix/sysv/linux/sh/bits/fcntl.h (fallocate): Likewise.
