[PATCH] s390: getdents patch for 32 -> 64 converter

[Sripathi Kodi]

Hi,
This patch solves a problem with working of getdents while using 32 bit 
binaries on 64 bit Linux/390. glibc expects d_type to be passed if we 
have a kernel version after 2.6.4, so we have to also handle it in the 
32bit syscall converter. Similar patch was given for PPC by Marcus 
Meissner 
(http://ozlabs.org/pipermail/linuxppc64-dev/2004-March/001359.html) and 
was integrated into 2.6.5.

Thanks,
Sripathi.
