Hello, I have a question regarding calling write() from an interrupt context in the kernel: is it possible ?
There is an article about reading/writing files from the kernel by GregKH; see: http://interactive.linuxjournal.com/article/8110 Everybody (including the author) admits that reading/writing files from the kernel is not recommended at all. Yet, because of my interest in this, I tried it and it works. However, when trying write() from interrupt context it will not work because write() can sleep. Is there a way to call write() from interrupt context ? some special filesystem or patch? I found a dumpfs patch; but it was not tested yet; moreover, it is a patch against 2.6.8-rc2 and as it seems it was abandoned. see http://lwn.net/Articles/94748/?format=printable Any ideas?
