Subject: [PATCH v3 0/6] introduce LED block device activity trigger
Date: Sun, 11 Aug 2019 02:54:57 +0900 [thread overview]
Message-ID: <1565459703-30513-1-git-send-email-akinobu.mita@gmail.com> (raw)
This work is inspired by the report on linux-nvme mailing list.
disk-activity trigger not working for nvme disk:
http://lists.infradead.org/pipermail/linux-nvme/2019-July/025253.html
This LED block device activity trigger works with any block devices.
* v3
- Avoid the name collision with LED_OFF and LED_ON
- Add ABI documentation
- Add more detail to Kconfig help text
* v2
- Remove "move declaration of led_stop_software_blink() to linux/leds.h" patch
- Move the trigger implementation to drivers/leds/trigger
- s/blk_ledtrig/ledtrig_blk/
- Add CONFIG_LEDS_TRIGGER_BLOCK
- Fix wrong bitops usages
- Add interface to stop and restart polling disk stats
- Stop polling disk stats for scsi disk during runtime suspend
Akinobu Mita (6):
block: umem: rename LED_* macros to MEMCTRL_LED_*
scsi: mvsas: rename LED_* enums to SGPIO_LED_*
scsi: nsp32: rename LED_* macros to EXT_PORT_LED_*
block: introduce LED block device activity trigger
ledtrig-blk: add interface to stop and restart polling disk stats
scsi: sd: stop polling disk stats by ledtrig-blk during runtime
