The brand new GCC 5.1.0 warns by default on using a boolean in the switch condition. This results in the following warning: fs/nfs/nfs4proc.c: In function 'nfs4_proc_get_rootfh': fs/nfs/nfs4proc.c:3100:10: warning: switch condition has boolean value [-Wswitch-bool] switch (auth_probe) { ^ This code was obviously using switch to make use of the fall-through semantics (without the usual comment, though). Rewrite that code using if statements to avoid the warning and make the code a bit more readable on the way.
