axeld + bonefish:

The return value of Inode::WaitForRequest() is status_t not bool. So the
method would always fail when it actually succeeded. This affected reads
from pipes which didn't have data. The bug was hidded since VFS code
mostly checks error codes only against < B_OK, so that such a read would
be treated as 0 byte read.
