Hi all,
After merging the vfs-brauner tree, today's linux-next build (powerpc
allyesconfig) produced these warnings:
samples/vfs/mountinfo.c: In function 'show_propagation':

Introduced by commits
0c8f746452aa ("samples: add a mountinfo program to demonstrate statmount()/listmount()")
ee8c840a4a35 ("samples: fix missing nodiratime option and handle propagate_from correctly")
I am not sure why these warnings only turned up today.
