[meta-filesystems][PATCH 4/5] xfstests: upgrade 2025.04.27 -> 2026.07.21

387 commits across 21 fortnightly releases (739 files changed,
+16397/-2042). 114 new tests added (xfs x44, generic x32, btrfs x16,
f2fs x14, ext4 x3, overlay x2, selftest x2, ceph x1) and one removed
(xfs/539).

Major themes:
 * Multi-block atomic writes: new common/atomicwrites, fio atomic-write
   helpers, fsx atomic-write support, and O_[D]SYNC / sudden-shutdown /
   bigalloc / hardware-AWU atomic tests.
 * XFS zoned / RT-device work: common/zoned with zloop helpers, zoned
   growfs, zone-alignment mkfs checks, zone GC low-space, external and
   internal realtime device support.
 * New xfs_healer test family (background repair service).
 * file_getattr(2)/file_setattr(2) support (new src/file_attr.c,
   AC_HAVE_FILE_GETATTR probe), VFS delegation tests, and a new
   fsnotify/fanotify error-reporting helper (src/fs-monitor.c).
 * Infrastructure: treewide $MOUNT_PROG -> _mount conversion, temp
   files moved to $TMPDIR, systemd-coredump collection in check.

Build-system: configure.ac gains AC_HAVE_FILE_GETATTR and a
btrfs_ioctl_received_subvol_args type check; src/Makefile adds
unlink-fsync, truncate, rw_hint, fs-monitor, btrfs_ioctl and a
conditional file_attr target. No new link libraries, so no DEPENDS
change is needed. LICENSE checksum unchanged.

Recipe patch changes:
 * Drop 0002-Drop-detached_mounts_propagation-and-remove-sys-moun.patch:
   its rationale (glibc sys/mount.h vs linux/mount.h clash reached via
   src/vfs/utils.c) no longer applies because utils.c no longer includes
   sys/mount.h, and the src/Makefile hunk no longer applied anyway.
 * Add 0001-locktest-do-not-tie-struct-delegation-to-the-F_GETDE.patch:
   glibc 2.43 defines F_GETDELEG/F_SETDELEG but neither glibc nor the
   kernel UAPI declares struct delegation, so tying the struct to the
   "#ifndef F_GETDELEG" guard leaves it undefined and locktest fails to
   build with "variable has incomplete type 'struct delegation'".

Also bump the bundled unionmount-testsuite by one commit
(dir-weird-open-dir.py adjusted to the upstream kernel).

+Subject: [PATCH] locktest: do not tie struct delegation to the F_GETDELEG
+ guard
+
+glibc 2.43 added F_GETDELEG/F_SETDELEG to <bits/fcntl-linux.h>, but it
+does not declare struct delegation and neither does the kernel UAPI.
+
+locktest.c defined struct delegation inside "#ifndef F_GETDELEG", which
+assumes that any libc providing the fcntl commands also provides the
+struct. On glibc 2.43+ the guard is taken, the struct is never defined
+and the build fails:
+
+  locktest.c:1065:20: error: variable has incomplete type 'struct delegation'
+  locktest.c:1365:23: error: variable has incomplete type 'struct delegation'
+  locktest.c:1615:20: error: variable has incomplete type 'struct delegation'
+
+Keep the F_GETDELEG/F_SETDELEG fallbacks guarded, but define the struct
+unconditionally since no libc declares it.
+
