Hi Namjae,

This v2 is ported to the Linux kernel tree and is based on current
mainline commit 8bc67e4db64a ("Merge tag 'erofs-for-7.1-rc5-fixes' of
git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs").  The
patches now modify fs/ntfs/super.c rather than the out-of-tree Github
layout.

The fixes cover mount failure cleanup, a free-cluster precalc allocation
failure path that can otherwise leave waiters blocked forever, and the
$UpCase default-table alias check.  Per review, the free-cluster patch
now avoids the temporary file_ra_state heap allocation entirely by using
a stack variable for the synchronous bitmap scan.

Testing:
- For patch 1, I built a DEBUG_KMEMLEAK/DEBUG_FS kernel and injected an
  ntfs_fill_super() failure immediately after load_system_files().  Before
  the fix, kmemleak reported the leaked volume label allocated from
  ntfs_ucstonls(); after the fix, the same failure path produced no
  kmemleak report.
- For patch 2, I used QEMU with a debug injection that forces the initial
  precalc readahead-state allocation to fail.  Before the fix, statfs
  remained blocked in D state in ntfs_statfs().  This version removes
  that heap allocation and therefore removes the injected failure point.
  I also mounted a fresh NTFS image with the stack-backed state and
  verified statfs reported the same free count as ntfsinfo -m.

Changes since v1:
- Rebased and regenerated the series for the Linux kernel tree
  (fs/ntfs/super.c), instead of the Github out-of-tree layout.
- Changed patch 2 to declare the temporary file_ra_state on the stack,
  as suggested by Hyunchul Lee, instead of adding an OOM fallback path.
- Zero-initialized patch 2's on-stack file_ra_state because
  file_ra_state_init() only initializes ra_pages and prev_pos.
- Reworded patch 3 to avoid overstating user-visible name comparison
  effects, and used memcmp() for the exact $UpCase table comparison.

  ntfs: free volume-wide resources on fill_super failure
  ntfs: avoid heap allocation for free-cluster readahead state
  ntfs: only alias volume $UpCase to default on exact match
