****************************************************************************

*
* WARNING: 'check-rpaths' detected a broken RPATH and will cause 'rpmbuild'
* to fail. To ignore these errors, you can set the '$QA_RPATHS'
* environment variable which is a bitmask allowing the values
* below. The current value of QA_RPATHS is 0x0000.
*
* 0x0001 ... standard RPATHs (e.g. /usr/lib); such RPATHs are a minor
* issue but are introducing redundant searchpaths without
* providing a benefit. They can also cause errors in multilib
* environments.
* 0x0002 ... invalid RPATHs; these are RPATHs which are neither absolute
* nor relative filenames and can therefore be a SECURITY risk
* 0x0004 ... insecure RPATHs; these are relative RPATHs which are a
* SECURITY risk
* 0x0008 ... the special '$ORIGIN' RPATHs are appearing after other
* RPATHs; this is just a minor issue but usually unwanted
* 0x0010 ... the RPATH is empty; there is no reason for such RPATHs
* and they cause unneeded work while loading libraries
* 0x0020 ... an RPATH references '..' of an absolute path; this will
break
* the functionality when the path before '..' is a symlink
*
*
* Examples:
* - to ignore standard and empty RPATHs, execute 'rpmbuild' like
* $ QA_RPATHS=$[ 0x0001|0x0010 ] rpmbuild my-package.src.rpm
* - to check existing files, set $RPM_BUILD_ROOT and execute check-rpaths
like
* $ RPM_BUILD_ROOT=<top-dir> /usr/lib/rpm/check-rpaths

Hi Kirby,
There are some significant changes to write-behind that went into repository
after 2.0.0rc4. Can you check with the latest code from repository or get
2.0.0rc6 from our internal releases at
http://ftp.gluster.com/pub/gluster/glusterfs/qa-releases/glusterfs-2.0.0rc6.
tar.gz
regards,

If you use flush-behind=on, it is a acceptable result that other client
machines will not see your operations immediately.
But it is not acceptable that the sequentially executed program cannot see
the result immediately caused by the prior one on the same client machine.
The later situation happens when I run rpmbuild over a glusterfs volume.
If I run following commands with flush-behind = on, some error happens.

You can see, the last 2 patch operates the same file "Makefile.org".

If I run each of the command above manually, everything goes right.
If the flush-behind is turned off, everything goes right too.
