This series fixes a few regressions introduced by the recent sysrq rework that went into 5.6.
The fix for the unnecessary per-character overhead probably could have been marked for stable but I left that decision to the maintainers as it is a bit intrusive (although mostly shuffling code around). Johan Changes in v2 - inline uart_unlock_and_check_sysrq() along with the other helpers (restoring the interrupt state in a helper was never an issue) Johan Hovold (3): Revert "serial: core: Refactor uart_unlock_and_check_sysrq()" serial: core: fix sysrq overhead regression serial: core: drop redundant sysrq checks drivers/tty/serial/serial_core.c | 96 +---------------------------- include/linux/serial_core.h | 102 +++++++++++++++++++++++++++++-- 2 files changed, 100 insertions(+), 98 deletions(-) -- 2.26.2
