-Subject: [PATCH] selftests: proc: include fcntl.h in proc-pidns
-
-proc-pidns.c uses open() and O_* flags, but does not include
-<fcntl.h>. This breaks the proc selftests build with errors such as:
-
-  error: implicit declaration of function 'open'
-  error: 'O_WRONLY' undeclared
-  error: 'O_CREAT' undeclared
-  error: 'O_RDONLY' undeclared
-
-Include <fcntl.h> to provide the declaration and flag definitions.
-
-Fixes: 5554d820f71c ("selftests/proc: add tests for new pidns APIs")
-Tested with:
-  make -C tools/testing/selftests TARGETS=proc
