Series block: Remove skd driver | expand

Commit Message

Damien Le Moal Feb. 4, 2021, 8:43 a.m. UTC
With the removal of the skd driver, using IRQ safe locking of a bdev
bd_size_lock spinlock to protect the bdev inode size is not necessary
anymore as there is no other known driver using this lock under an IRQ
disabled context (e.g. calling set_capacity() with IRQ disabled).
Revert commit 0fe37724f8e7 ("block: fix bd_size_lock use") which
introduced the IRQ safe change.

Do you mean "if #1 in this series is accepted" ?
I have not received patch #1... I wonder if it hit the list ? Did you get it ?

Patch 1 is 111KB... Probably too big and it gets dropped by vger.

I generated it with "git rm" and a few other changes (MAITAINERS, Kconfig and
Makefile). Is it possible to shorten the "git rm" part so that it does not show
every single line removed but just the files being deleted ? That driver is a
single file, so very large.

Well that's bad, but how could you remove the driver then if vger doesn't  like it?
