#tech-kern, I need your help. I have updated the repository [1] (moving to cvs soon). Most of current details are in the README.
First of all, I'd love to hear any comments and/or suggestions. Second, I am seeking volunteers to build and test the patch. Next, I ran into an issue when trying to send a DIOCACHESYNC ioctl to a vnd. The lwp hangs, probably trying to obtain some lock taken previously, but that's just my guess. I might be doing something wrong, if anyone has clues, please help. Finally, I was looking for some more explanation about this [2]. I was trying to at least produce mentioned race, but couldn't. Thank you in advance. Przemyslaw Sierocinski [1] http://sourceforge.net/p/fsscrubflags/code/ci/master/tree/ [2] http://nxr.netbsd.org/xref/src/sys/ufs/ffs/ffs_inode.c#299
