From: Shahar Shitrit <redacted> Extract the health reporter recovery abort logic into a separate function devlink_health_recover_abort(). The function encapsulates the conditions for aborting recovery: - When auto-recovery is disabled - When previous error wasn't recovered - When within the grace period after last recovery Signed-off-by: Shahar Shitrit <redacted> Reviewed-by: Jiri Pirko <redacted> Reviewed-by: Carolina Jubran <redacted> Signed-off-by: Tariq Toukan <tariqt@nvidia.com> --- net/devlink/health.c | 31 +++++++++++++++++++++++-------- 1 file changed, 23 insertions(+), 8 deletions(-)
