vboxsf (Guest Additions 6.1.16) fails to compile on CentOS 8 Stream (kernel 4.18.0-257)

Hi.

This issue is similar to https://www.virtualbox.org/ticket/19112.

vboxsf.ko can not be compiled due to error "MS_REMOUNT undeclared".

I fixed it by removing the lines

​https://github.com/mdaniel/virtualbox-org-svn-vbox-trunk/blob/88de9c9135ffa2ff100ce64931417aa8144afa76/src/VBox/Additions/linux/sharedfolders/vfsmod.c#L48

and

in /opt/VBoxGuestAdditions-6.1.16/src/vboxsf/vfsmod.c

and then running 'make' and 'make install' (in src folder).

Screenshot with the error will be attached.

A correction:

and then running 'make' and 'make install' (in src folder).

and then running 'make' and 'make install' (in src/vboxguest-6.1.16 folder).

I have just seen the ticket https://www.virtualbox.org/ticket/20091.

Evidently, this ticket is a duplicate of 20091.
