[RFC PATCH v2 0/4] Proposal to add eventfd option to --decode-fds

[Sahil Siddiq]

Hi,

Currently, the --decode-fds option hasn't been implemented for
eventfd file descriptors. Having this option can help examine the
value of the eventfd counter that is associated with an eventfd
file descriptor. This is especially useful when multiple threads
or processes utilise (reading, writing, etc.) file descriptors
corresponding to the same eventfd object.

This proposal also includes a patch to implement this option.

Thanks,
Sahil

Changes v1 -> v2:
- src/filter_qualify.c
  (parse_inject_token): Shift changes from patch #2 to patch #1.
- src/util.c
  (parse_fdinfo_efd_id): New function.
  (printeventfd): Retrieve eventfd-id. Implement "else" branch.
