| |
When CONFIG_TRACING is disabled, the new preemptirq events tracer produces a build failure:
In file included from kernel/trace/trace_irqsoff.c:17:0: kernel/trace/trace.h: In function 'trace_test_and_set_recursion': kernel/trace/trace.h:542:28: error: 'struct task_struct' has no member named 'trace_recursion'
Adding an explicit dependency avoids the broken configuration.
Fixes: d59158162e03 ("tracing: Add support for preempt and irq enable/disable events") Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- No idea if this is the best solution, it just happened to fix the build failure for me. --- kernel/trace/Kconfig | 1 + 1 file changed, 1 insertion(+)
