This commit has been processed because it contains a "Fixes:" tag fixing commit: 2482ddec670f ("mm: add SLUB free list pointer obfuscation").
The bot has tested the following trees: v5.5.8, v5.4.24, v4.19.108, v4.14.172.
v5.5.8: Build failed! Errors: mm/slub.c:262:4: error: implicit declaration of function ‘swab’; did you mean ‘swap’? [-Werror=implicit-function-declaration]
Eek; this must be missing an include that is implicit from something recent? I will investigate...
swab() didn't exist "back then" :) It was introduced by d5767057c9a7 ("uapi: rename ext2_swab() to swab() and share globally in swab.h"). I can just take that patch to stable kernels.
