Subject: [PATCH 00/19 v6.1.y] Backport minmax.h updates from v6.17-rc7
This series backports 19 patches to update minmax.h in the 6.1.y branch,
aligning it with v6.17-rc7.
The ultimate goal is to synchronize all longterm branches so that they
include the full set of minmax.h changes.
Previous work to update 6.12.48:
https://lore.kernel.org/stable/20250922103123.14538-1-farbere@amazon.com/T/#t
and 6.6.107:
https://lore.kernel.org/stable/20250922103241.16213-1-farbere@amazon.com/T/#t
The key motivation is to bring in commit d03eba99f5bf ("minmax: allow
min()/max()/clamp() if the arguments have the same signedness"), which
is missing in older kernels.
In mainline, this change enables min()/max()/clamp() to accept mixed
argument types, provided both have the same signedness. Without it,
backported patches that use these forms may trigger compiler warnings,
which escalate to build failures when -Werror is enabled.
Andy Shevchenko (1):
minmax: deduplicate __unconst_integer_typeof()
David Laight (8):
minmax: fix indentation of __cmp_once() and __clamp_once()
minmax.h: add whitespace around operators and after commas
minmax.h: update some comments
minmax.h: reduce the #define expansion of min(), max() and clamp()
minmax.h: use BUILD_BUG_ON_MSG() for the lo < hi test in clamp()
minmax.h: move all the clamp() definitions after the min/max() ones
minmax.h: simplify the variants of clamp()
minmax.h: remove some #defines that are only expanded once
Herve Codina (1):
minmax: Introduce {min,max}_array()
Linus Torvalds (8):
minmax: avoid overly complicated constant expressions in VM code
minmax: simplify and clarify min_t()/max_t() implementation
minmax: make generic MIN() and MAX() macros available everywhere
minmax: add a few more MIN_T/MAX_T users
minmax: simplify min()/max()/clamp() implementation
minmax: don't use max() in situations that want a C constant
expression
minmax: improve macro expansion and type checking
minmax: fix up min3() and max3() too
Matthew Wilcox (Oracle) (1):
minmax: add in_range() macro
