BPF series proposes user-memory mmap and copy kfuncs
Sleepable helpers would let programs create executable anonymous mappings and write into the current task without the no-fault limits of probe_write_user.

BPF series adds sleepable kfuncs to map and write user memory
Proposed helpers would let privileged BPF programs allocate anonymous pages, including executable ones, and fault in copies into the current process.
By oopsBPF gains by-value struct and __int128 argument support
A verifier and JIT series lets global functions and kfuncs take small scalar aggregates without the old rejections and register miscounts.
By oopsBPF gains 16-byte aggregate returns via R0:R2 pair
Kernel verifier and JITs learn LLVM 23's convention so subprograms and kfuncs can return __int128 and small structs by value.
