| Subject: vc: create vcs(a) devices for consoles |
| |
| From: Kay Sievers <kay.sievers@vrfy.org> |
| |
| commit c46a7aec556ffdbdb7357db0b05904b176cb3375 upstream. |
| |
| The buffer for the consoles are unconditionally allocated at con_init() |
| time, which miss the creation of the vcs(a) devices. |
| |
| Since 2.6.30 (commit 4995f8ef9d3aac72745e12419d7fbaa8d01b1d81, 'vcs: |
| hook sysfs devices into object lifetime instead of "binding"' to be |
| exact) these devices are no longer created at open() and removed on |
| close(), but controlled by the lifetime of the buffers. |
