Hi everyone, The Linux Coda drivers and the ext3 patches don't seem to get along very well, at least in Linux 2.4.7. I've got a stock 2.4.7 kernel with a patch applied to the USB drivers (for a sony digital camera; see http://www.sujal.net/tech/linux/ just a change in unusual_devs.h). After I applied the ext3 patches from http://www.uow.edu.au/~andrewm/linux/ext3/ . Basically,

I'm running a bit late with the e-mail this time around, but I think that's ok since there really isn't any major new features here - the bulk of the Ocfs2 update is bug fixes, or cleanups. The same goes for configfs. The only two things that could be described as features would be: - Sunil has updated Ocfs2 to provide even more live cluster locking information via debugfs. - Joel

i_alloc_sem has always been a bit of an odd "lock". It''s the only remaining rw_semaphore that can be released by a different thread than the one that locked it, and it''s use case in the core direct I/O code is more like a counter given that the writers already have external serialization. This series removes it in favour of a simpler counter scheme, thus getting rid

It''s been nearly a year since the patches needed to implement a reflinked copy between subvolumes have been posted (http://permalink.gmane.org/gmane.comp.file-systems.btrfs/9865 ) and I still get "Invalid cross-device link" error with Linux 3.2.4 while I try to do a cp --reflink between subvolumes.
