| |
Hello.
Though I posted the following patch a week ago, there is no objection, and Kame-san reviewed it.
I hope merge it by someone if possible. (I don't find maintainer's name for procfs.)
--- I changed the return value to ENOENT. This return value is then returned when opening the proc entry that have been removed. For example, open("/proc/bus/pci/XX/YY") during the corresponding device is being hot-removed.
