[PATCH 18/20] Re: [2.6-BK-URL] NTFS 2.1.17 release

[Anton Altaparmakov]

This is patch 18/20 in the series.  It contains the following ChangeSet:

<aia21@xxxxxxxxxx> (04/08/17 1.1824)
   NTFS: Only need two spare runlist elements when reallocating memory in
   fs/ntfs/lcnalloc.c::ntfs_cluster_alloc(), not three since we no longer
   add a starting element.
   
   Signed-off-by: Anton Altaparmakov <aia21@xxxxxxxxxx>

Best regards,

	Anton
