mm: rework accept memory helpers

2024-09-02T03:26:07+00:00

Make accept_memory() and range_contains_unaccepted_memory() take 'start' and 'size' arguments instead of 'start' and 'end'. Remove accept_page(), replacing it with direct calls to accept_memory(). The accept_page() name is going to be used for a different function. Link: https://lkml.kernel.org/r/20240809114854.3745464-6-kirill.shutemov@linux.intel.com Signed-off-by: Kirill A.

memblock test: fix implicit declaration of function 'isspace'

2024-08-06T05:21:25+00:00

Commit 1e4c64b71c9b ("mm/memblock: Add "reserve_mem" to reserved named memory at boot up") introduce usage of isspace(). Let's include in kernel.h to fix this.

memblock test: fix implicit declaration of function 'memparse'

2024-08-06T05:21:25+00:00

Commit 1e4c64b71c9b ("mm/memblock: Add "reserve_mem" to reserved named memory at boot up") introduce the usage of memparse(), which is not defined in memblock test. Add the definition and link it to fix the build. Signed-off-by: Wei Yang Link: https://lore.kernel.org/r/20240806010319.29194-3-richard.weiyang@gmail.com Signed-off-by: Mike Rapoport (Microsoft)

tools/testing: abstract two init.h into common include directory

2024-08-06T05:17:50+00:00

Currently we have two test suits define its own init.h. This is a little redundant. Let's create a init.h in common include directory and merge these two into it.

memblock tests: include export.h in linkage.h as kernel dose

2024-08-06T05:17:49+00:00

In kernel code, linkage.h includes export.h. Let's sync with kernel. This is a preparation for move init.h in common include directory.

2024-08-06T05:17:49+00:00

In kernel code, memory_hotplug.h is included in mmzone.h instead of in init.h. Let's sync with kernel. This is a preparation for move init.h in common include directory.

memblock tests: add memblock_reserve_many_may_conflict_check()

2024-06-05T07:22:22+00:00

This may trigger the case fixed by commit 48c3b583bbdd ("mm/memblock: fix overlapping allocation when doubling reserved array"). This is done by adding the 129th reserve region into memblock.memory. If memblock_double_array() use this reserve region as new array, it fails.
