[Mesa-dev] [PATCH] mesa/glthread: correctly comparae thread handles

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

As mentioned in the manual - comparing pthread_t handles via the C
comparison operator is incorrect and pthread_equal() should be used
instead.

Fixes: d8d81fbc316 ("mesa: Add infrastructure for a worker thread to process GL commands.")
