could make kernel panic.

Log load and replay is part of the metadata handle flow during mount
operation. The $MFT record will be loaded and used while replaying logs.
However, a malformed $MFT record, say, has RECORD_FLAG_DIR flag set and
contains an ATTR_ROOT attribute will misguide kernel to treat it as a
directory, and try to free the allocated resources when the
corresponding inode is freed, which will cause an invalid kfree because
the memory hasn't actually been allocated.

Syzbot reports a NULL dereference in ni_write_inode.
When creating a new inode, if allocation fails in mi_init function
(called in mi_format_new function), mi->mrec is set to NULL.
In the error path of this inode creation, mi->mrec is later
dereferenced in ni_write_inode.

Add a NULL check to prevent NULL dereference.

If the member struct INDEX_BUFFER *index of struct indx_node is
incorrect, that is, the value of __le32 used is greater than the value
of __le32 total in struct INDEX_HDR. Therefore, OOB read occurs when
memmove is called in indx_insert_into_buffer().
Fix this by adding a check in hdr_find_e().

Above issue may happens as follows:

  mi_init
    mi->mrec = kmalloc(sbi->record_size, GFP_NOFS); -->failed to allocate memory
      if (!mi->mrec)
        return -ENOMEM;
iput

      ntfs_evict_inode
        ni_write_inode
	  is_rec_inuse(ni->mi.mrec)-> As 'ni->mi.mrec' is NULL trigger NULL-ptr-deref

To solve above issue if new inode failed make inode bad before call 'iput()' in
'ntfs_new_inode()'.

If the MFT record of ntfs inode is not a base record, inode->i_op can be
NULL. And a null-ptr-deref may happen:

ntfs_lookup()
    dir_search_u() # inode->i_op is set to NULL
    d_splice_alias()
        __d_add()
            d_flags_for_inode() # inode->i_op->get_link null-ptr-deref

Fix this by adding a Check on inode->i_op before calling the
d_splice_alias() function.

Label ATTR_ROOT in ntfs_read_mft() sets is_root = true and
ni->ni_flags |= NI_FLAG_DIR, then next attr will goto label ATTR_ALLOC
and alloc ni->dir.alloc_run. However two states are not always
consistent and can make memory leak.

 1) attr_name in ATTR_ROOT does not fit the condition it will set
 is_root = true but NI_FLAG_DIR is not set.
 2) next attr_name in ATTR_ALLOC fits the condition and alloc
 ni->dir.alloc_run
 3) in cleanup function ni_clear(), when NI_FLAG_DIR is set, it frees
 ni->dir.alloc_run, otherwise it frees ni->file.run
 4) because NI_FLAG_DIR is not set in this case, ni->dir.alloc_run is
 leaked as kmemleak reported:

Pull xfs percpu counter fixes from Darrick Wong:
 "We discovered a filesystem summary counter corruption problem that was
  traced to cpu hot-remove racing with the call to percpu_counter_sum

  dying cpus and hence misses those counter values if the cpu shutdown
  hooks have not yet run to merge the values.

  I'm hoping this is a fairly painless fix to the problem, since the
  dying cpu mask should generally be empty. It's been in for-next for a
  week without any complaints from the bots.

   - Fix a race in the percpu counters summation code where the

 "This batch started with some debugging enhancements to the new

  As for more serious code changes -- there's a bug fix to make the
  lockless allocator scan the whole filesystem before resorting to the
  locking allocator. We're also adding a selftest for the venerable
  directory/xattr hash function to make sure that it produces consistent
  results so that we can address any fallout as soon as possible.

   - Add a few debugging assertions so that people (me) trying to port
     code to the new allocator functions don't mess up the caller
     requirements

   - Relax some overly cautious lock ordering enforcement in the new
     allocator code, which means that file allocations will locklessly
     scan for the best space they can get before backing off to the
     traditional lock-and-really-get-it behavior

If user does forced unmount ("umount -f") while files are still open
on the share (as was seen in a Kubernetes example running on SMB3.1.1
mount) then we were marking the share as "TID_EXITING" in umount_begin()
which caused all subsequent operations (except write) to fail ... but
unfortunately when umount_begin() is called we do not know yet that
there are open files or active references on the share that would prevent
unmount from succeeding.  Kubernetes had example when they were doing
umount -f when files were open which caused the share to become
unusable until the files were closed (and the umount retried).

Fix this so that TID_EXITING is not set until we are about to send
the tree disconnect (not at the beginning of forced umounts in
umount_begin) so that if "umount -f" fails (due to open files or
references) the mount is still usable.

Get rid of any prefix paths in @path before lookup_positive_unlocked()
as it will call ->lookup() which already adds those prefix paths
through build_path_from_dentry().

This has caused a performance regression when mounting shares with a
prefix path where readdir(2) would end up retrying several times to
open bad directory names that contained duplicate prefix paths.

Fix this by skipping any prefix paths in @path before calling
lookup_positive_unlocked().

Performance tests with large number of threads noted that the change
of the default closetimeo (deferred close timeout between when
close is done by application and when client has to send the close
to the server), to 5 seconds from 1 second, significantly degraded
perf in some cases like this (in the filebench example reported,
the stats show close requests on the wire taking twice as long,
and 50% regression in filebench perf). This is stil configurable
via mount parm closetimeo, but to be safe, decrease default back
to its previous value of 1 second.
