Subject: [GIT PULL] Remove uninitialized_var() for v5.9-rc1
Hi Linus,
Please pull this uninitialized_var() macro removal series for v5.9-rc1.
This is long overdue, and has hidden too many bugs over the years. The
series has several "by hand" fixes, and then a trivial treewide
replacement. As you might imagine, this had a few conflicts while
living in -next. Resolution is easy, of course: just remove any
uninitialize_var() wrappings, but if you want to see the specifics,
they are:
kernel/debug/kdb/kdb_io.c

https://lore.kernel.org/linux-next/20200703143550.7ebbe771@canb.auug.org.au/
net/ipv6/ip6_flowlabel.c
https://lore.kernel.org/linux-next/20200727192721.53af345a@canb.auug.org.au/
drivers/infiniband/core/uverbs_cmd.c
https://lore.kernel.org/linux-next/20200728184520.5634a0a0@canb.auug.org.au/
If you prefer, I can rebase and re-run my script, but your default
position has been to let you deal with conflicts, so here we are. :)
Thanks!
-Kees
