This revision addresses a reliability problems (failure during unmount)
on older kernels.  It adds a facility for generating directory streams,
and uses that to test various historic readdir and readdir_r bugs.  This
revealed a bunch of other problems, which had to be fixed to get clean
test results for dirent/tst-readdir-long in particular.

The <support/readdir.h> abstraction allows testing various readdir
variants (we have six of them on some architectures) in a single test,
with a simple for loop, instead of using skeleton files.  The new
<support/xdirent.h> header is more along traditional lines and provides
x* wrappers.

Thanks,
Florian

Florian Weimer (13):
  Bundle <linux/fuse.h> userspace header from Linux 6.10
  support: Add <support/xdirent.h>
  Linux: readdir_r needs to report getdents failures (bug 32124)
  support: Add <support/readdir.h>
  support: Add FUSE-based file system test framework to support/
  misc: FUSE-based tests for mkstemp
  io: Add FUSE-based test for fchmod
  io: Add tst-lstat-nofollow, tst-lstat-nofollow-time64
  dirent: Add tst-closedir-leaks
  Linux: Use readdir64_r for compat __old_readdir64_r (bug 32128)
  dirent: Add tst-readdir-long
  dirent: Add tst-rewinddir
  Linux: readdir64_r should not skip d_ino == 0 entries (bug 32126)
