shmem: fix compilation warnings on unused functions
Compiling shmem.c with SHMEM and TRANSAPRENT_HUGE_PAGECACHE enabled raises warnings on two unused functions when CONFIG_TMPFS and CONFIG_SYSFS are both disabled: mm/shmem.c:390:20: warning: `shmem_format_huge' defined but not used [-Wunused-function] static const char *shmem_format_huge(int huge) ^~~~~~~~~~~~~~~~~ mm/shmem.c:373:12: warning: `shmem_parse_huge' defined but not used [-Wunused-function] static int shmem_parse_huge(const char *str) ^~~~~~~~~~~~~~~~ A conditional compilation on tmpfs or sysfs removes the warnings.
