man/man2/mremap.2: fix incorrect reference to VM_MIXEDMAP

[PATCH] man/man2/mremap.2: fix incorrect reference to VM_MIXEDMAP

Posted by Lorenzo Stoakes 1 week, 3 days ago

We actually disallow VM_DONTEXPAND and VM_PFNMAP for VM_DONTUNMAP, the
manpage incorrectly references VM_MIXEDMAP. Correct this.

Of course I ironically typo'd here :)

VM_DONTUNMAP -> MREMAP_DONTUNMAP

Thanks!  I've applied the patch, with the amendment.  I've also added CC
tags for all the people in CC.

Use port 80 (that is, <...:80/>).
