      erofs: reserve physical_clusterbits[] · 54e0b6c8
      Gao Xiang authored
      Formal big pcluster design is actually more powerful / flexable than
      the previous thought whose pclustersize was fixed as power-of-2 blocks,
      which was obviously inefficient and space-wasting. Instead, pclustersize
      can now be set independently for each pcluster, so various pcluster
      sizes can also be used together in one file if mkfs wants (for example,
      according to data type and/or compression ratio).
      
      Let's get rid of previous physical_clusterbits[] setting (also notice
      that corresponding on-disk fields are still 0 for now). Therefore,
      head1/2 can be used for at most 2 different algorithms in one file and
      again pclustersize is now independent of these.

      smb3: fix cached file size problems in duplicate extents (reflink) · cfc63fc8
      Steve French authored
      There were two problems (one of which could cause data corruption)
      that were noticed with duplicate extents (ie reflink)
      when debugging why various xfstests were being incorrectly skipped
      (e.g. generic/138, generic/140, generic/142). First, we were not
      updating the file size locally in the cache when extending a
      file due to reflink (it would refresh after actimeo expires)
      but xfstest was checking the size immediately which was still
      0 so caused the test to be skipped.  Second, we were setting
      the target file size (which could shrink the file) in all cases
      to the end of the reflinked range rather than only setting the
      target file size when reflink would extend the file.

      cifs: Silently ignore unknown oplock break handle · 219481a8
      Vincent Whitchurch authored
      Make SMB2 not print out an error when an oplock break is received for an
      unknown handle, similar to SMB1.  The debug message which is printed for
      these unknown handles may also be misleading, so fix that too.
      
      The SMB2 lease break path is not affected by this patch.
      
      Without this, a program which writes to a file from one thread, and
      opens, reads, and writes the same file from another thread triggers the
      below errors several times a minute when run against a Samba server
      configured with "smb2 leases = no".
