Hi All,
The latest mainline kernel branch fails to build mips sb1250_swarm_defconfig with
the error:
kernel/cgroup/cgroup.c: In function 'cgroup_local_stat_show':
kernel/cgroup/cgroup.c:3699:15: error: implicit declaration of function 'cgroup_tryget_css'; did you mean 'cgroup_tryget'? [-Werror=implicit-function-declaration]
3699 | css = cgroup_tryget_css(cgrp, ss);
| ^~~~~~~~~~~~~~~~~
| cgroup_tryget
kernel/cgroup/cgroup.c:3699:13: warning: assignment to 'struct cgroup_subsys_state *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
3699 | css = cgroup_tryget_css(cgrp, ss);
| ^
git bisect pointed to d1d4ff5d11a5 ("cgroup: put cgroup_tryget_css() inside CONFIG_CGROUP_SCHED").
Reverting the commit has fixed the build failure.
I will be happy to test any patch or provide any extra log if needed.
#regzbot introduced: d1d4ff5d11a5887a9c4cfc00294bc68ba03e7c16
