(backport <rust-lang#4178>) (cherry picked from commit af7e126)
This lint was recently added so this change is needed to fix CI. The suggested alternative is to use `ptr::fn_addr_eq` which isn't available until 1.85, so allow the lint here. (backport <rust-lang#4177>) (cherry picked from commit 99f4dd9)

`PF_BLOCK_TS` and `PF_SUSPEND_TASK`. They are also added to the tests. Interestingly, `PF_SUSPEND_TASK` is already there somewhere in the build script 🤔 Signed-off-by: Paul Mabileau <paul.mabileau@harfanglab.fr> (backport <rust-lang#4174>) (cherry picked from commit 6934e52)
