Subject: [PATCH 8/8] random: Wake up all getrandom(2) callers when pool is
|
||
|
|
ready
|
||
|
|
|
||
|
|
If more than one application invokes getrandom(2) before the pool
|
||
|
|
is ready, then all bar one will be stuck forever because we use
|
||
|
|
wake_up_interruptible which wakes up a single task.
|
||
|
|
|
||
|
|
This patch replaces it with wake_up_all.
