[PATCH v3 1/6] fs/proc/kcore: drop KCORE_REMAP and KCORE_OTHER
From: David Hildenbrand <hidden>
Date: 2021-05-26 09:31:08
Also in:
linux-fsdevel, linux-mm, lkml, virtualization
Subsystem:
filesystems (vfs and infrastructure), kcore, proc filesystem, the rest · Maintainers:
Alexander Viro, Christian Brauner, Omar Sandoval, Linus Torvalds
Commit db779ef67ffe ("proc/kcore: Remove unused kclist_add_remap()")
removed the last user of KCORE_REMAP.
Commit 595dd46ebfc1 ("vfs/proc/kcore, x86/mm/kcore: Fix SMAP fault when
dumping vsyscall user page") removed the last user of KCORE_OTHER.
Let's drop both types. While at it, also drop vaddr in "struct
kcore_list", used by KCORE_REMAP only.
