fcntl16.c patch
PATCH 1/1 fcntl16.c patch
The fcntl16 testcase is being compiled twice, once normal, and the other time with the _FILE_OFFSET_BITS=64 define set.
When compiled with 64bit file functions (as fcntl16_64) all file functions will automatically use their 64bit variants, e.g. "struct flock64" instead of "struct flock".
So, when in the code e.g.
fcntl(fd, F_SETLK, thislock)
is called, this will automatically be translated into
fcntl64(fd, F_SETLK64, thislock)
and "thislock" needs to be of type "struct flock64".
So, we need to make sure that thislock is of the correct type, with the start and len fields being of type "off_t" which then will be translated into "loff_t" during compilation when _FILE_OFFSET_BITS=64 is set.
This fixes the fcntl16_64 testcase on hppa64-linux-gnu with 32bit userspace running on 64bit kernel.

What about using struct flock as defined in bits/fcntl.h instead?

Patch is attached.I would be happy if you would apply one of those.
Applied, thanks.
And it would be easier for me if you had send git formatted patch with headline and description (output from git format-patch).
