Subject: [PATCH] lib/fatal-signal: Drop logging of failed dummy backtrace.
|
|
|
|
Some systems may provide backtrace() in libc but for some reason
|
|
not provide any frames when attempting to use it.
|
|
|
|
On those systems the fatal_signal_init() function currently logs
|
|
this debug message: "Capturing of dummy backtrace has failed."
|
|
|
|
A consequence of this logging may be false negative test results.
|
|
|
|
Logging the fact that backtrace() does not work has limited value
|
|
on a production system and I propose we drop it.
|
|
|
|
Fixes: 759a29dc2d97 ("backtrace: Extend the backtrace functionality.")
