Description Jeff Layton 2010-11-10 09:13:46 EST

A number of bug fixes have been merged upstream since RHEL6.0 was branched and patched. This bug is to track merging them.

Comment 1 RHEL Product and Program Management 2010-11-18 13:19:32 EST

This request was evaluated by Red Hat Product Management for inclusion
in a Red Hat Enterprise Linux maintenance release. Product Management has 
requested further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed 
products. This request is not yet committed for inclusion in an Update release.

Comment 6 yanfu,wang 2011-05-06 02:13:52 EDT

hi Jeff,
I found there's different from the patch http://patchwork.usersys.redhat.com/patch/29746/ when build kernel-2.6.32-112.el6 src package.
For example, the patch shown as below:
diff --git a/fs/cifs/cifsproto.h b/fs/cifs/cifsproto.h
...
 extern struct cifsFileInfo *cifs_new_fileinfo(struct inode *newinode,
 				__u16 fileHandle, struct file *file,
-				struct vfsmount *mnt, unsigned int oflags);
+				struct vfsmount *mnt, unsigned int oflags,
+				__u32 oplock);


and the patch applied result shown as below after using rpmbuild -bp:
extern struct cifsFileInfo *cifs_new_fileinfo(__u16 fileHandle,
                                struct file *file, struct tcon_link *tlink,
                                __u32 oplock);


Is there anything I'm missing?

Comment 7 Jeff Layton 2011-05-06 07:14:05 EDT

Yes, you're missing looking at the later patches in the set. There are several patches that touch the same places in the code.

thanks, I found the vfsmount pointer is removed from cifsFileInfo against comment #6 in http://patchwork.usersys.redhat.com/patch/30051/ which fixed in bug 656461.

set it SanityOnly and have run some nfs regression testing, pls refer to the errata's comments.
