The add_device_randomness() function calls mix_pool_bytes() twice for the input pool and the non-blocking pool, for a total of four times. By using _mix_pool_byte() and taking the spinlock in add_device_randomness(), we can halve the number of times we need take each pool's spinlock. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> |
