Merge branch 'mm/mkstemps-mode-for-packfiles'
* mm/mkstemps-mode-for-packfiles: Use git_mkstemp_mode instead of plain mkstemp to create object files git_mkstemps_mode: don't set errno to EINVAL on exit. Use git_mkstemp_mode and xmkstemp_mode in odb_mkstemp, not chmod later. git_mkstemp_mode, xmkstemp_mode: variants of gitmkstemps with mode argument. Move gitmkstemps to path.c Add a testcase for ACL with restrictive umask.
