[RFC PATCH v5 0/8] fuse: caches documentation and testing

[Luis Henriques]

Hi!

Following this email, I'm sending v5 of this patchset.  Here's what changed
since v4 (mostly from Amir's review):

- Included suggested changes to the document
- Moved back 'struct fuse_common_ctx' into tests FIXTURE
- Fixed a few typos in the tests comments
- Added missing SPDX-License-Identifier tag to fuse_common.h
- Added an initial stab on the dentries cache (hence not adding Amir's
  'Reviewed-by' tag in the first patch)

Luis Henriques (8):
  Documentation: fuse: add document on caches being used by FUSE
  selftests/fuse: convert fusectl test to fuse3
  selftests/fuse: check that fusectlfs is mounted
  selftests/fuse: factor-out test fixture setup/teardown
  selftests/fuse: use dynamically allocated memory to store ACLs
  selftests/fuse: add some extra ACL caching tests
  selftests/fuse: add fuse symlink caching test
  selftests/fuse: add fuse readdir caching test
