Bugs encountered when using Oracle ACFS with Linux samba on Rhel

First, the environment introduction:
The results of the cat/etc/issue are:

Red Hat Enterprise Linux Server release 6.5 (Santiago) Kernel \ r on an \m

Detailed patch information for GI: only 11.2.0.4 version of GI installed, no GI PSU hit any, no GI patch

Ii. description of the issue:
This is a set of rhel6.5 RAC, using the Oracle GI cluster software, using ACFS,ACFS to do the rhel6.5 file system (mount point for/xxx, as below),

EXPDP out the DMP file to the/xxx mount point. At the same time, the/xxx mount point is set to share with samba, shared to the Windows Host (hereinafter referred to as the Windows Samba client),
The application software will perform a series of processing (Zip, and so on) for DMP in the/xxx file system on this Windows Samba client.

The following problems are found in the process of use:
Access on Windows Samba clients (access method is the Vip\ share name in Windows Start-run: \\rac) when the shared space is very slow.

I searched for MoS and saw an article that reads "ACFS on 11.2.0.4 and samba" for search keywords in MoS search,
There is an article in "Community search results": ACFS on 11.2.0.4 and Samba (community forum ID 3574416)
An SR (SR 3-11146797451) was subsequently submitted and confirmed by the analysis of the Dalian GCS Engineer: The phenomenon is 11.2.0.4 version of the GI bug that requires a patch fix
This patch is: Patch 17696547

In fact, the patch is not so good to hit. The middle is also a bit tortuous ... Because it is a colleague dozen patches, the details of which I am not very clear, just heard not very well.
