| |
Hi,
I was looking at the usage of bdevname(), cdevname(), and kdevname(), and noticed that they each return a pointer to a static buffer. This buffer contains a formatted device name, which is typically printed immediately following the call. However, I don't see any explicit lock protection for these buffers.
For SMP systems, is there something implicit in their use that prevents a race on these buffers? Has anyone seen garbled device names being printed (which might be attributed to a race)?
