Subject: [PATCH] Fix FileIOThread concurrency issues
|
|
|
|
FileIOThread was using two volatile counters in order to track if
|
|
any pending work was in the queue, this causes potential concurrency
|
|
issues when this counter is updated from multiple threads, potentially
|
|
causing these counters to desync due to the unsafe volatile update
