src/patches/suse-2.6.27.25/patches.fixes/ocfs2-initialize-count-before-generic_write_checks

   1 From: Goldwyn Rodrigues <rgoldwyn@suse.de>
   2 Subject: Initialize count in aio_write before generic_write_checks
   3 References: bnc#517098
   4
   5 generic_write_checks() expects count to be initialized to the size of
   6 the write.
   7 Writes to files open with O_DIRECT|O_LARGEFILE write 0 bytes because
   8 "count" is uninitialized.
