[libcamera-devel] [PATCH v2 0/3] Camera3RequestDescriptors std::map => std::queue

[Umang Jain]

As per the extended design discussion for libcamera HAL, this series
addresses the part I of the design that will lead to new iterations
for async post-processor eventually.

The series mainly ports storage of Camera3RequestDescriptor from
std::map => queue while fixing out-of-order request completion from
abortRequest(). The series also accounts for a singular location to
send back capture results to the framework (find sendCaptureResults()).

The series has been validated on CTS: 230 / 231
(carrying [PATCH v3 0/1] android: Wait on acquisition fences in
CameraStream)

\wip: Checkstyle isn't happy with 2/3's camera_device.h, not sure why! 

Changes in v2:
- Use queue instead of deque
- Fix a race between abortRequest() and queuing a descriptor in 2/3
- address general comments in v1 review.

Umang Jain (3):
  android: camera_worker: Use Camera3RequestDescriptor as cookie
  android: camera_device: Transform descriptors_ map to queue
  android: camera_device: Send capture results by inspecting the queue
