Subject: [for-linus][PATCH 2/2] tracefs: remove stale update_gid code
From: Linus Torvalds <torvalds@...ux-foundation.org>
The 'eventfs_update_gid()' function is no longer called, so remove it
(and the helper function it uses).
Link: https://lore.kernel.org/all/CAHk-=wj+DsZZ=2iTUkJ-Nojs9fjYMvPs1NuoM3yK7aTDtJfPYQ@mail.gmail.com/
Fixes: 8186fff7ab64 ("tracefs/eventfs: Use root and instance inodes as default ownership")
