This lists all fields of the `struct fd_ops` when object of that type -- `handler_fd_ops` in server/signal.c -- is being initialized.
It looks like field list in initialization of the `handler_fd_ops` in server/signal.c was out-of-sync for a long time. Take a look, for example, on patches ad1e0609a0f (server: Get rid of no loner used cancel_async from fd_ops., 2016-12-01) (which removed "reference" to the `cancel_async` field correctly, but did not add "references" to the `read` and `write` fields, for example), or 837b39b2028 (server: Add read and write fd member functions., 2015-05-05) (which updated `struct fd_ops` but did not change initialization of the `handler_fd_ops` at all).
Because the main purpose of initialization of the `handler_fd_ops` made in server/signal.c is to assign address of the `handler_poll_event()` function to the `poll_event` field, while making all other fields `NULL`ed, lacking some fields in that initialization is not an error according to C standard:
6.7.11 Initialization
11 ... If an object that has static or thread storage duration is not initialized explicitly, or any object is initialized with an empty initializer, then it is subject to default initialization, which initializes an object as follows:
- if it has pointer type, it is initialized to a null pointer;
...
22 If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate is subject to default initialization.
But to maintain code consistency I believe initialization of the `handler_fd_ops` object should enumerate all fields of the `struct fd_ops` type.
No functional changes intended.
