[PATCH 0/3] ntfs: fix mount failure cleanup and free-count setup

[DaeMyung Kang]

Hi Namjae,

This small series is based on current ntfs-next commit d8756162c6ca
("ntfs: remove unsupported quota handling").

The previous quota_ino reference leak fix is intentionally dropped
because that commit removes load_and_init_quota(), the $Quota/$Q state,
and the quota out-of-date marker path.

The remaining fixes cover mount failure cleanup, a free-cluster precalc
OOM path that can otherwise leave waiters blocked forever, and the
$UpCase default-table alias check.  The free-cluster patch also clears
the per-bitmap-page free counters on the conservative zero-free-count
path so later allocation heuristics stay conservative after the known
flag is published.

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(); after the fix, the waiter
  woke up and statfs returned with the conservative zero free-cluster
  count.

DaeMyung Kang (3):
  ntfs: free volume-wide resources on fill_super failure
  ntfs: wake free-cluster waiters when precalc allocation fails
  ntfs: only alias volume $UpCase to default on exact match
