Description: buffer overruns could theoretically occur
Details    : llapi_semantic_traverse() modifies the "path" argument by
             appending values to the end of the origin string, and a buffer
             overrun may occur. Adding buffer overrun check in liblustreapi.

r=adilger,nathan
- fixed possible divide by zero in ldlm_pools_shrink();

set stripecount correctly

Remove ancient tag file.

Move $RUNAS initialization until after cfg parsing so that $RUNAS_ID can
be set in the cfg file.  Use "error" instead of "echo".

Description: e2fsck reports "invalid unused inodes count"
Details    : If a new ldiskfs filesystem is created with the "uninit_groups"
	     feature and only a single inode is created in a group then the
	     "bg_unused_inodes" count is incorrectly updated.  Creating a
	     second inode in that group would update it correctly.

SAVE_PWD fix; 32a, 32b 35 fixes: disk1_4 correct path, correct FSNAME.

. "false conflicts" may cause file contention and switching to lockless i/o
. compilation warning on a 64-bit platform
. contention reports are recorded as lustre errors
. llap_from_page complains about wrong llap_checksums for lockless pages
. assertions needed to be sure that ll_releasepage is called on pages with
  locks only
. NS_DEFAULT_CONTENDED_LOCKS=0 was considered as wrong default value

and, the lockless read/write is disabled by default now.
