Hi Al and Linus,
currently a lot of the file system calls in the early in code (and the
devtmpfs kthread) rely on the implicit set_fs(KERNEL_DS) during boot.
This is one of the few last remaining places we need to deal with to kill
off set_fs entirely, so this series adds new helpers that take kernel
pointers. These helpers are in init/ and marked __init and thus will
be discarded after bootup. A few also need to be duplicated in devtmpfs,
though unfortunately.
The series sits on top of my previous
"decruft the early init / initrd / initramfs code v2"
Could you fold the fixes in the parent branch to avoid the bisect hazards?
As it is, you have e.g. "initd: pass a non-f_pos offset to kernel_read/kernel_write"
that ought to go into "initrd: switch initrd loading to struct file based APIs"...
I'm not a huge fan of rebasing after it has been out for a long time and
with pending other patches on top of it. But at your request I've now
folded the fixes and force pushed it.
