[LTP] [PATCH v11 0/4] futex: Add error coverage tests for wait, wake and cmp_requeue

[Michael Menasherov]

Improve error handling coverage for futex syscalls by adding tests
for missing error conditions that were previously untested.

v11:
- Fix alignment to match open parenthesis in multi-line function calls

v10:
- Fix doc comment in futex_cmp_requeue03 to mention both EFAULT and
  EACCES outcomes for the PROT_NONE case

v9:
- Use compile-time testcase arrays with double pointers instead of
  runtime initialization in setup()
- Fix sparse warnings: add (void *) cast in SAFE_MUNMAP calls
- Remove unnecessary braces in single-statement if blocks

Michael Menasherov (4):
  futex_wait06: Add EFAULT error coverage test
  futex_wait07: Add EINTR error coverage test
  futex_wake05: Add EFAULT error coverage test
  futex_cmp_requeue03: Add EFAULT error coverage test
