A-reiserfs_panic-noreturn.patch
   adds call to panic() in reiserfs_panic(). This call is actually never
   reached, but it makes gcc happy and supresses compilation warning.

B-reiserfs_do_truncate-pathrelse.patch
   adds pathrelse() in "PAP-5660" error path of reiserfs_do_truncate().

C-reiserfs_get_block-cleanup.patch
   cleanups in reiserfs_get_block():
    . reserve enough space in transaction
    . avoid "plug hole" race
    . add cast to "new_offset"
    . add 825 number to unnamed vs- error message

D-blockalloc-for-disk-90%full.patch
   patch to disable "border algorithm" when disk is nearly full.
   This is believed to improve performance.
