Subject: [PATCH v4 0/3] System call design: preadv & pwritev.
Date: Thu, 18 Dec 2008 12:42:19 +0100 [thread overview]
Message-ID: <1229600542-11585-1-git-send-email-kraxel@redhat.com> (raw)
Hi folks,
Guess I have your attention now thanks to LWN ;)
Next round of the preadv & pwritev patch series, hopefully finally
solving the architecture issues. I've decided to go with the suggestion
from the s390 guys: split the 64bit offset into two explicitly coded
32bit halves. The syscall prototype should work now for all archs
without (in-kernel) wrappers. glibc must wrap the syscalls though to
hide that split from the applications. But there is no way around glibc
wrappers anyway, so I think that is sensible decision.
cheers,
Gerd
