mm: remove unused totalram_pages_inc() and totalram_pages_dec()

2026-09-06T03:22:23+00:00

totalram_pages_inc() and totalram_pages_dec() have had no callers since commit 7fbc5e26123e ("memblock: extract page freeing from free_reserved_area() into a helper") and commit 287b89773d81 ("powerpc/pseries/cmm: Use adjust_managed_page_count() insted of totalram_pages_*"), respectively. Remove them. Drop the totalram_pages_inc() stub from tools mm.h too.

tools/nolibc: validate directory with O_DIRECTORY in opendir()

2026-08-31T20:51:17+00:00

fdopendir() requires a call to fstat() to determine if the opened file is a directory. Currently opendir() inherits this extra syscall. Switch to O_DIRECTORY and remove the call to fdopendir() in opendir() to make the directory type check cheaper.

tools/nolibc: verify that a directory is opened

2026-08-31T20:51:06+00:00

If a non-directory is opened, ENODIR should be returned from opendir()/fdopendir() right away and not only during readdir_r(). Validate the type of opened file during open.

tools/nolibc: Add sendfile()

2026-08-31T04:19:24+00:00

This is useful because it allows copying data up to 2GB from one fd to another without a buffer in userspace and with a single syscall. For 32bit kernels we use the sendfile64 syscall to allow for 64bit offsets to work.

tools/nolibc: add support for hexagon

A mostly straightforward new architecture with a few quirks: * Only qemu-user is supported for testing. * Clang is required for compilation. * -fsanitize=undefined is broken.
