I'm trying to figure it out how to automatically get the correct subsystem string for putting on the first line of the commit message / subject of the patch message. For example: Subject: [PATCH 001/142] arch/x86: Replace memcpy with struct assignment ^^^^^^^^^^ arch/x86 is only the first two levels of directories from Kernel source. This may not be smart enough... What should be the subsystem for the files: arch/x86/kernel/e820.c drivers/acpi/thermal.c drivers/atm/idt77105.c drivers/block/xen-blkfront.c drivers/media/dvb-core/dvb_frontend.c drivers/media/usb/pvrusb2/pvrusb2-v4l2.c drivers/misc/phantom.c drivers/misc/sgi-gru/grufault.c drivers/net/usb/hso.c drivers/net/wireless/at76c50x-usb.c drivers/scsi/ncr53c8xx.c drivers/sh/intc/core.c drivers/staging/iio/light/tsl2x7x_core.c fs/btrfs/tree-defrag.c fs/cifs/connect.c fs/devpts/inode.c net/bridge/netfilter/ebtables.c net/ceph/auth_x.c net/rds/ib_send.c sound/pci/bt87x.c sound/soc/codecs/wm8994.c sound/usb/caiaq/audio.c get_maintainers.pl helps but not a lot. Here is it's output for the files above: arch/x86/kernel/e820.c:X86 ARCHITECTURE (32-BIT AND 64-BIT) drivers/acpi/thermal.c:ACPI THERMAL DRIVER drivers/atm/idt77105.c:ATM drivers/block/xen-blkfront.c:XEN HYPERVISOR INTERFACE drivers/media/dvb-core/dvb_frontend.c:MEDIA INPUT INFRASTRUCTURE (V4L/DVB) drivers/media/usb/pvrusb2/pvrusb2-v4l2.c:PVRUSB2 VIDEO4LINUX DRIVER drivers/misc/phantom.c:SENSABLE PHANTOM drivers/misc/sgi-gru/grufault.c:SGI GRU DRIVER drivers/net/usb/hso.c:HSO 3G MODEM DRIVER drivers/net/wireless/at76c50x-usb.c:NETWORKING [WIRELESS] drivers/scsi/ncr53c8xx.c:SCSI SUBSYSTEM drivers/sh/intc/core.c:ARM/SHMOBILE ARM ARCHITECTURE drivers/staging/iio/light/tsl2x7x_core.c:STAGING - INDUSTRIAL IO fs/btrfs/tree-defrag.c:BTRFS FILE SYSTEM fs/cifs/connect.c:COMMON INTERNET FILE SYSTEM (CIFS) fs/devpts/inode.c:THE REST net/bridge/netfilter/ebtables.c:EBTABLES net/ceph/auth_x.c:CEPH DISTRIBUTED FILE SYSTEM CLIENT net/rds/ib_send.c:RDS - RELIABLE DATAGRAM SOCKETS sound/pci/bt87x.c:BT87X AUDIO DRIVER sound/soc/codecs/wm8994.c:WOLFSON MICROELECTRONICS DRIVERS sound/usb/caiaq/audio.c:NATIVE INSTRUMENTS USB SOUND INTERFACE DRIVER Subject: [PATCH] NATIVE INSTRUMENTS USB SOUND INTERFACE DRIVER: Replace memcpy with struct assignment Do not look as good option too. It is possible to use full path of the file but leads to Subject over 80 chars. Any ideas? -- Peter
