Hi, I actually already sent a patch for this:
https://patchwork.freedesktop.org/patch/378202/
I'm guessing it hasn't gotten picked up upstream yet?

for an error by checking if it is less than zero, and hence this

Introduce "memfd_secret" system call with the ability to create memory
areas visible only in the context of the owning process and not mapped not
only to other processes but in the kernel page tables as well.
The user will create a file descriptor using the memfd_secret()

It will be used by the upcoming secret memory implementation.

Removing a PAGE_SIZE page from the direct map every time such page is
allocated for a secret memory mapping will cause severe fragmentation of
the direct map. This fragmentation can be reduced by using PMD-size pages
as a pool for small pages for secret memory mappings.

Hi,
This is an implementation of "secret" mappings backed by a file descriptor.
v2 changes:
* Follow Michael's suggestion and name the new system call 'memfd_secret'
* Add kernel-parameters documentation about the boot option
* Fix i386-tinyconfig regression reported by

The definition of PMD_PAGE_ORDER denoting the number of base pages in the
second-level leaf page is already used by DAX and maybe handy in other
cases as well.
Several architectures already have definition of PMD_ORDER as the size of
second level page table, so to avoid
