Subject: [PATCH v2 0/4] io_uring: text representation of opcode in trace
Date: Mon, 25 Apr 2022 08:07:36 -0700	[thread overview]
Message-ID: <20220425150740.2826784-1-dylany@fb.com> (raw)

This series adds the text representation of opcodes into the trace. This
makes it much quicker to understand traces without having to translate
opcodes in your head.

Patch 1 adds a type to io_uring opcodes
Patch 2 is the translation function.
Patch 3 is a small cleanup
Patch 4 uses the translator in the trace logic

v2:
 - return "INVALID" rather than UNKNOWN/LAST
 - add a type to io_uring opcdodes to get the compiler to complain if any are
   missing

Dylan Yudaken (4):
  io_uring: add type to op enum
  io_uring: add io_uring_get_opcode
  io_uring: rename op -> opcode
  io_uring: use the text representation of ops in trace
