[PATCH liburing v1 0/2] liburing micro-optimzation

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

From: Ammar Faizi <ammarfaizi2@gnuweeb.org>

Hi Jens,

This series contains liburing micro-optimzation. There are two patches
in this series:

## Patch 1
- Fix bloated memset due to unexpected vectorization.
  Clang and GCC generate an insane vectorized memset() in nolibc.c.
  liburing doesn't need such a powerful memset(). Add an empty inline ASM
  to prevent the compilers from over-optimizing the memset().

## Patch 2
- Simplify `io_uring_register_file_alloc_range()` function.
  Use a struct initializer instead of memset(). It simplifies the C code
  plus effectively reduces the code size.
