Linux 5.9.4
Greg Kroah-Hartman
maintainerI'm announcing the release of the 5.9.4 kernel.
This is only a bugfix for the 5.9.3 kernel release which had some problems with some symlinks for the powerpc selftests. This problem was caused by issues in going from git->patch->quilt->git and things got a bit messed up. To resolve this, I reverted the offending patch and a prerequsite one, and then used 'git cherry-pick' to backport the patches properly, which preserved the links correctly.
Many thanks to Marc Aurèle La Franc and others for helping me notice this and provide some solutions for it.
If you had no issues with these files in 5.9.3, no need to upgrade at this time.
The updated 5.9.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.9.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

I find this strange. There is only 4 commits in git between 5.9.3 and 5.9.4 while the review had 391 patches. Is it normal ?
Best regards,

Did you read the email before this in the series explaining what this release was for? :)
The "next" release should have all 391 patches, give me time to catch up...
thanks,
