Installation of GuestAddition 6 on RHEL6 fails -> duplicate of #18238

[toracat]

Building the vboxsf kernel module fails on RHEL6 guest.

/vboxsf/vfsmod.c: In function ‘sf_show_options’:
/vboxsf/vfsmod.c:509: error: dereferencing pointer to incomplete type
/vboxsf/vfsmod.c:515: error: implicit declaration of function ‘seq_printf’
/vboxsf/vfsmod.c:518: error: implicit declaration of function ‘seq_puts’
/vboxsf/vfsmod.c:519: error: implicit declaration of function ‘seq_escape’

This is due to missing header files:

 <linux/mount.h>
 <linux/seq_file.h>

It was reported in the following forum post:

The attached patch fixes the errors.

Patch to fix vboxsf build errors on RHEL6

This issue was reported in bug #18238 as well.

I thought I had seen that "seq_file.h" before, when I first looked at your ticket, I just couldn't remember where! ;)

Good eye!

Either #18249 is a duplicate of #18238, or #18238 is a duplicate of #18249.

"This bugtracker isn't big for both of them!" :)

Marking this ticket as a duplicate. Please try the current test builds<1> and update #18238 if appropriate.

I confirm the fix. With VBoxGuestAdditions_6.0.1-128006, vboxsf builds fine on RHEL-6.
