The patch titled MNT_UNBINDABLE fix has been removed from the -mm tree. Its filename was mnt_unbindable-fix.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: MNT_UNBINDABLE fix From: "Andries E. Brouwer" <Andries.Brouwer@xxxxxx> Some time ago ( http://lkml.org/lkml/2007/6/19/128 ) I wrote about MNT_UNBINDABLE that it felt like a bug that it is not reset by "mount --make-private". Today I happened to see mount(8) and Documentation/sharedsubtree.txt and both document the version obtained by applying the little patch given in the above (and again below). So, the present kernel code is not according to specs and must be regarded as buggy. Specification in Documentation/sharedsubtree.txt: See state diagram: unbindable should become private upon make-private. Specification in mount(8): ... It's also possible to set up uni-directional propagation (with --make- slave), to make a mount point unavailable for --bind/--rbind (with --make-unbindable), and to undo any of these (with --make-private).
