365b1818 ("add f_flags to struct statfs(64)") resized f_spare within
struct statfs which caused a UML crash. There is no need to copy f_spare.Signed-off-by: Richard Weinberger

In case of mode mismatch, do *not* blindly close the descriptor
another openers might be using right now. Open the underlying
file with currently sufficient mode, then
* if current mode has grown so that it's sufficient for
us now, just close our new fd
* if current mode has grown and our fd is *not* enough
to cover it, close and repeat.
* otherwise, install our fd if the file hadn't been
opened at all or dup2() our fd over the current one (and close
our fd).
Critical section is protected by mutex; yes, system-wide. All
we do under it is a bunch of comparison and maybe an overwriting
dup2() on host.Signed-off-by: Al Viro

fs/hostfs/hostfs_user.c defines do_readlink() as non-static, and so does
fs/xfs/linux-2.6/xfs_ioctl.c when CONFIG_XFS_DEBUG=y. So rename
do_readlink() in hostfs to hostfs_do_readlink().I think it's better if XFS guys will also rename their do_readlink(),
it's not necessary to use such a general name.Signed-off-by: WANG Cong

To convert from tv_nsec to tv_usec, one needs to divide by 1000, not multiply.

This patch allows hostfs_setattr() to work on unlinked open files by calling
set_attr() (the userspace part) with the inode's fd.Without this, applications that depend on doing attribute changes to unlinked
open files will fail.It works by using the fd versions instead of the path ones (for example
fchmod() instead of chmod(), fchown() instead of chown()) when an fd is
available.Signed-off-by: Alberto Bertogli

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
