[PATCH 10/35] attr: rename function and struct related to checking attributes

From
Stefan Beller <sbeller@google.com>
Date
Nov 10, 2016, 20:34 UTC
Message-ID
<20161110203428.30512-11-sbeller@google.com>
In-Reply-To
<20161110203428.30512-1-sbeller@google.com>
From: Junio C Hamano <gitster@pobox.com>

The traditional API to check attributes is to prepare an N-element array of "struct git_attr_check" and pass N and the array to the function "git_check_attr()" as arguments.

In preparation to revamp the API to pass a single structure, in which these N elements are held, rename the type used for these individual array elements to "struct git_attr_check_elem" and rename the function to "git_check_attrs()".
