On a FreeBSD 5.0 the behaviour of screen when connecting to other users sessions have changed. Previously: 1. login as userA start a screen as userA and disconnect 2. login as root su - userA "screen -r" 3. result failure as userA cant access the ttyX with such a message Current: 1. login as userA start a screen as userA and disconnect 2. login as root su - userA "screen -r" 3.

...process to signal that vnodes are available (10% of the vnodes need to be freed). Under our test, none of the nodes meet the criteria for freeing, so the vnlru process goes to sleep for 3 seconds without signaling anything. Then it wakes, tries again, same result. Current constraints are: - v_type is not VNON or VBAD - v_object is NULL or v_object->resident_page_count < trigger - VMIGHTFREE(vp) is true - can acquire vp->v_interlock I tried adding code which uses only the following constraints if no nodes could be freed the previous time: - VMIGHTFREE(vp) is true - can acqui...

Hi, Since almost all operations in the FUSE low-level API identify files by inode number, I''ve been using zfs_zget() to get the corresponding znode/vnode in order to call the corresponding VFS function in zfs_vnops.c. However, there are some cases when zfs_zget() behaves slightly different than I need: 1) If zp->z_unlinked != 0 then zfs_zget() returns ENOENT. I need it to return

Hi all, I was intending on trying out gjournal on a new disk i've added in my desktop. I had a look to see what the most recent patch provided by Pawel and found http://people.freebsd.org/~pjd/patches/gjournal6_20061024.patch I created the directories as per Pawel's original post (http://lists.freebsd.org/pipermail/freebsd-fs/2006-June/001962.html) and the patch succeeded with no failed
