Subject: [PATCH liburing v1 0/2] Makefile and t/no-mmap-inval updates

Hi Jens,

There are two patches in this series:

1. Makefile: Remove the `partcheck` target.

Remove the `partcheck` target because it has remained unused for nearly
four years, and the associated TODO comment has not been actioned since
its introduction in commit:

  b57dbc2d308a849 ("configure/Makefile: introduce libdevdir defaults to $(libdir)")


2. t/no-mmap-inval: Replace `valloc()` with `t_posix_memalign()`.

Address the limitations of valloc(). This function, which is primarily
used for allocating page-aligned memory, is not only absent in some
systems but is also marked as obsolete according to the `man 3 valloc`.

Replace valloc() with t_posix_memalign() to fix the following build
error:

  no-mmap-inval.c:28:56: warning: call to undeclared function 'valloc'; ISO C99 and \
  later do not support implicit function declarations [-Wimplicit-function-declaration]
          p.cq_off.user_addr = (unsigned long long) (uintptr_t) valloc(8192);
                                                                ^
  1 warning generated.
