[RFC 1/4] mm: remove unused TASK_SIZE_OF()
From: Dmitry Safonov <hidden>
Date: 2016-12-31 06:35:33
Also in:
linux-arm-kernel, linuxppc-dev, lkml, sparclinux
Subsystem:
arm64 port (aarch64 architecture), linux for powerpc (32-bit and 64-bit), mips, parisc architecture, s390 architecture, scheduler, sparc + ultrasparc (sparc/sparc64), the rest, x86 architecture (32-bit and 64-bit) · Maintainers:
Catalin Marinas, Will Deacon, Madhavan Srinivasan, Michael Ellerman, Thomas Bogendoerfer, "James E.J. Bottomley", Helge Deller, Heiko Carstens, Vasily Gorbik, Alexander Gordeev, Ingo Molnar, Peter Zijlstra, Juri Lelli, Vincent Guittot, "David S. Miller", Andreas Larsson, Linus Torvalds, Thomas Gleixner, Borislav Petkov, Dave Hansen
All users of TASK_SIZE_OF(tsk) have migrated to mm->task_size or
TASK_SIZE_MAX since:
commit d696ca016d57 ("x86/fsgsbase/64: Use TASK_SIZE_MAX for
FSBASE/GSBASE upper limits"),
commit a06db751c321 ("pagemap: check permissions and capabilities at
open time"),
