This is useful in deployments in which a clean panic is preferable to an indefinite stall. ---------------------------------------------------------------- Rik van Riel (1): smp,csd: Throw an error if a CSD lock is stuck for too long Documentation/admin-guide/kernel-parameters.txt | 7 +++++++ kernel/smp.c | 13 ++++++++++++- 2 files changed, 19 insertions(+), 1 deletion(-)
