Hello,
Recently I noticed substantial audio dropouts when listening to MP3s in
`cmus` while doing big and churny `git checkout` commands in my linux git
tree.
It's not something I've done much of over the last couple months so I

Hello,
I've been working on some graphics hacks which has me paying close
attention to frame rates. Something I've noticed recently in the 4.13
cycle is a seemingly random loss of ~40% frame rate. These are purely
software-rendered hacks, and I haven't spent much time trying to figure out

Attempted to play with BFQ but after building with CONFIG_IOSCHED_BFQ=y I'm

I'm not sure about this one, but never experienced it prior to 4.11.0-rc8.
During boot sometimes the home.mount unit fails and `systemctl status
home.mount` reports that the mount failed due to it already being busy.
I'm able to fix it by simply issuing `systemctl restart home.mount` from the

Hello all,
I'd like to propose a new system call, I know I'll probably be flamed,
but here goes.
Today there is no way to get a process which has been orphaned, and thus
become a child of init, back as a child of another process. This is
annoying me, please allow me to explain why.
