------------------------------------------------------ From: WangYuli wangyuli@uniontech.com Subject: mm: vmscan: avoid signedness error for GCC 5.4 Date: Wed, 7 May 2025 12:08:27 +0800

To the GCC 5.4 compiler, (MAX_NR_TIERS - 1) (i.e., (4U - 1)) is unsigned, whereas tier is a signed integer.

Then, the __types_ok check within the __careful_cmp_once macro failed, triggered BUILD_BUG_ON.

Use min_t instead of min to circumvent this compiler error.

Fix follow error with gcc 5.4: mm/vmscan.c: In function `read_ctrl_pos': mm/vmscan.c:3166:728: error: call to `__compiletime_assert_887' declared with attribute error: min(tier, 4U - 1) signedness error
