[LTP] [PATCH] flock07: Initialiaze the sigaction structure

Martin Doucha mdoucha@suse.cz
Wed Feb 5 11:19:36 CET 2025


The sigaction structure for child SIGUSR1 handler was uninitialized,
which sometimes resulted in SA_RESTART flag being enabled by accident
and the child flock() call never returning. Make sure the sigaction
structure is properly initialized.
