I wonder if we can say this in a bit more generic fashion.
A successful write to this file does not guarantee a successful
set of this limit to the value written into the file. This can
be due to a number of factors, such as rounding up to page
boundaries or the total availability of memory on the system.
The user is required to re-read this file after a write to
guarantee the value committed by the kernel.
This keeps a user from saying "I page aligned the value I stuck in
there, no I don't have to check it."
