This is not new -- I also saw it about 2 weeks ago but did not analyze or report it. use of PDE_DATA() (from <linux/proc_fs.h>): drivers/net/wireless/hostap/hostap_ap.c:85:2: error: implicit declaration of function 'PDE_DATA' [-Werror=implicit-function-declaration] fs/afs/proc.c:193:2: error: implicit declaration of function 'PDE_DATA' [-Werror=implicit-function-declaration] drivers/block/pktcdvd.c:2598:2: error: implicit declaration of function 'PDE_DATA' [-Werror=implicit-function-declaration] fs/ext4/super.c:1809:2: error: implicit declaration of function 'PDE_DATA' [-Werror=implicit-function-declaration] fs/ext4/mballoc.c:2263:9: error: implicit declaration of function 'PDE_DATA' [-Werror=implicit-function-declaration] fs/jbd2/journal.c:982:2: error: implicit declaration of function 'PDE_DATA' [-Werror=implicit-function-declaration] net/sunrpc/cache.c:1465:9: error: implicit declaration of function 'PDE_DATA' [-Werror=implicit-function-declaration] drivers/char/ipmi/ipmi_si_intf.c:2842:2: error: implicit declaration of function 'PDE_DATA' [-Werror=implicit-function-declaration] drivers/gpu/drm/drm_proc.c:66:9: error: implicit declaration of function 'PDE_DATA' [-Werror=implicit-function-declaration] net/can/proc.c:381:2: error: implicit declaration of function 'PDE_DATA' [-Werror=implicit-function-declaration] net/can/bcm.c:229:2: error: implicit declaration of function 'PDE_DATA' [-Werror=implicit-function-declaration] Al, would it make sense to have a stub for PDE_DATA() in <linux/proc_fs.h> when CONFIG_PROC_FS is not enabled? -- ~Randy -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
