[$] Development statistics for the 6.10 kernel

The 6.10 kernel was released
on July 14 after a nine-week development cycle. This time around,
13,312 non-merge changesets were pulled into the mainline repository — the
lowest changeset count since 5.17 in early 2022. Longstanding tradition
says that it is time for LWN to gather some statistics on where the new
code for 6.10 came from and how it got to the mainline; read on for the
details.
