** Description changed:
[Impact]
While debugging bug 1910277, I found that the test compilation will
- print some warnings on F/G:
- memfd_test.c:64:7: warning: implicit declaration of function ‘open’;
- memfd_test.c:90:6: warning: implicit declaration of function ‘fcntl’
- memfd_test.c:397:6: warning: implicit declaration of function ‘fallocate’;
- fuse_test.c:67:6: warning: implicit declaration of function ‘fcntl’
- fuse_test.c:261:7: warning: implicit declaration of function ‘open’;
+ print some warnings:
+ memfd_test.c:64:7: warning: implicit declaration of function ‘open’;
+ memfd_test.c:90:6: warning: implicit declaration of function ‘fcntl’
+ memfd_test.c:397:6: warning: implicit declaration of function ‘fallocate’;
+ fuse_test.c:67:6: warning: implicit declaration of function ‘fcntl’
+ fuse_test.c:261:7: warning: implicit declaration of function ‘open’;
It's harmless but fixing this we can make the test report easier to
read.
[Fix]
* 1c49e3783f8899 ("selftests/memfd: Fix implicit declaration warnings")
- This fix can be cherry-picked into F/G and compiled without any problem.
+ This fix can be cherry-picked into F/F-oem-5.6/G and compiled without any
problem.
Older kernel does not have this issue since they're missing some other
commits.
[Test Case]
Build the memfd test in kselftests with:
- sudo make TARGETS=memfd
+ sudo make TARGETS=memfd
With this fix, these warnings will be gone.
[Where problems could occur]
This fix is just for fixing the test case compilation, so it's not
affecting real kernel functionality.
** No longer affects: linux-oem-5.10 (Ubuntu)
