5MIME-Version: 1.0
6Content-Type: text/plain; charset=UTF-8
7Content-Transfer-Encoding: 8bit

9The gettid syscall was introduced in Linux 2.4.11. This is old enough
10that we can assume it always exists and thus not bother with the
11conditional backcompat logic.

4Subject: [PATCH] linux-user: rename gettid() to sys_gettid() to avoid clash
5 with glibc
6MIME-Version: 1.0
7Content-Type: text/plain; charset=UTF-8
8Content-Transfer-Encoding: 8bit
9
10The glibc-2.29.9000-6.fc31.x86_64 package finally includes the gettid()
11function as part of unistd.h when __USE_GNU is defined. This clashes
12with linux-user code which unconditionally defines this function name
13itself.

32While we could make our definition conditional and rely on glibc's impl,
33this patch simply renames our definition to sys_gettid() which is a
34common pattern in this file.
