linux-next: build warning after merge of the vfs tree

[Stephen Rothwell]

Hi Al,

After merging the vfs tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

kernel/signal.c: In function 'C_SYSC_rt_sigaction':
kernel/signal.c:3405:19: warning: unused variable 'mask' [-Wunused-variable]
   compat_sigset_t mask;
                   ^

Introduced by commit

  fc271087ebcb ("signal: replace sigset_to_compat() with put_compat_sigset()")
