I'm announcing the release of the 4.19.98 kernel.
All users of the 4.19 kernel series must upgrade.
The updated 4.19.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.19.y
and can be browsed at the normal kernel.org git web browser:
https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h

efi: Fix debugobjects warning on 'efi_rts_work'
[ Upstream commit ef1491e791308317bb9851a0ad380c4a68b58d54 ]
The following commit:
9dbbedaa6171 ("efi: Make efi_rts_work accessible to efi page fault handler")
converted 'efi_rts_work' from an auto variable to a global variable.
However, when submitting the work, INIT_WORK_ONSTACK() was still used,
causing the following complaint from debugobjects:
ODEBUG: object 00000000ed27b500 is NOT on stack 00000000c7d38760, but annotated.
Change the macro to just INIT_WORK() to eliminate the warning.

Incorrectly how? Fuzz off, or it shouldn't be applied at all? Should
this be reverted, or just fixed up, and if fixed up, do you have a patch
to fix it?

Just reverted. It applies to 9dbbedaa6171 which moved the efi_rts_work
off the stack, but is not in v4.19.y, so efi_rts_work is still a local
and needs the INIT_WORK_ONSTACK annotation.

Ok, thanks, will go revert this and push out a new release with that
fix, thanks for letting me know.

Wait, that commit happened back in 4.19.41 which was released in May
2019, so I don't think this is a rush, right? I'll just queue it up for
the next release instead of pushing out a rush one, thanks.
