SubjectRe: threaded FS-drivers
Hello!

In article <m0xzU5P-001DCmC@valiant.koehntopp.de> you write:
>[...]

Have a look at the fcntl(2) man page. I think Linux has already
supported POSIX style locks on parts of files for a long time (since
when the version numbers begun with 1., at least) :-)

But I think the thread was about the in kernel locking mechanisms
to protect transactions in the filesystem implementation from concurrent
operations.

Regards, Felix.
