From: Hans Holmberg <hans.holmberg@xxxxxxxxxxxx> This patchset adds trace events for tracking the internal state of pblk. I've used the events extensively the last few months, and they have proven very useful. The patches depend on some of Javier's for-4.20 patches. For ordering, see: Branch: for-4.20/pblk Remote: ssh://github.com/OpenChannelSSD/linux Hans Holmberg (4): lightnvm: pblk: add trace events for chunk states lightnvm: pblk: add trace events for line state changes lightnvm: pblk: add trace events for pblk state changes lightnvm: pblk: add tracing for chunk resets drivers/lightnvm/pblk-core.c | 69 ++++++++++++++++++- drivers/lightnvm/pblk-gc.c | 8 +++ drivers/lightnvm/pblk-init.c | 8 +++ drivers/lightnvm/pblk-recovery.c | 6 ++ drivers/lightnvm/pblk-trace.h | 145 +++++++++++++++++++++++++++++++++++++++ drivers/lightnvm/pblk-write.c | 10 ++- drivers/lightnvm/pblk.h | 14 ++++ 7 files changed, 256 insertions(+), 4 deletions(-) create mode 100644 drivers/lightnvm/pblk-trace.h -- 2.7.4
