[Minios-devel] [UNIKRAFT PATCH v2 0/2] Fix wrong round_page formula

[Vlad-Andrei BĂDOIU (78692) <vlad_andrei.badoiu@xxxxxxxxxxxxxxx>]

The code taken from OSv has the PAGE_MASK defined
as (PAGE_SIZE-1) whereas we have it defined as
(~((__PAGE_SIZE) - 1)). This causes end_pos to
be < new_size an such we're not allocating enough
memory for the file (new_size should always be
bigger than end_pos since're we're round upwards).

Changes from v1:
*) Created a new header, page.h,  that has the round up and down
macros
*) Updated the vfscore,ramfs and vfscore code to work
with the new header.

Vlad-Andrei Badoiu (2):
  include/uk: Add page.h
  lib/ramfs,vfscore,ukallocbbudy: Change the macro in vfscore and
    buddyalloc
