1999-12-05With soft updates, some buffers will be remarked as dirty after being written.Artur Grabowski
Handle this when syncing filesystems when unmounting. From NetBSD.
1999-12-05Use VONSYNCLIST to see if we should remove a vnode from the sync list insteadArtur Grabowski
of looking at v_dirtyblkhd.

disappear (detach is coming).
1999-05-31New struct statfs with mount options. NOTE: this replaces statfs(2),Todd C. Miller
fstatfs(2), and getfsstat(2) so you will need to build a new kernel before doing a "make build" or you will get "unimplemented syscall" errors. The new struct statfs has the following featuires: o Has a u_int32_t flags field--now softdep can have a real flag. o Uses u_int32_t instead of longs (nicer on the alpha). Note: the man page used to lie about setting invalid/unused fields to -1. SunOS does that but our code never has. o Gets rid of f_type completely. It hasn't been used since NetBSD 0.9 and having it there but always 0 is confusing. It is conceivable that this may cause some old code to not compile but that is better than silently breaking. o Adds a mount_info union that contains the FSTYPE_args struct. This means that "mount" can now tell you all the options a filesystem was mounted with. This is especially nice for NFS. Other changes: o The linux statfs emulation didn't convert between BSD fs names and linux f_type numbers. Now it does, since the BSD f_type number is useless to linux apps (and has been removed anyway) o FreeBSD's struct statfs is different from our (both old and new) and thus needs conversion. Previously, the OpenBSD syscalls were used without any real translation. o mount(8) will now show extra info when invoked with no arguments. However, to see *everything* you need to use the -v (verbose) flag.

1998-12-05Framework for generating automatic test code for locking disciplineConstantine Sapuntzakis
in DIAGNOSTIC mode. Added documentation to vfs_subr.c on locking needs of a couple calls. Improvements to the vinvalbuf patch. We need to start over after we let our pants down.
1998-12-04VFS-Lite2 requires stricter locking around vnode buffer queues. vinvalbufConstantine Sapuntzakis
had insufficient protection

1998-11-12Integrate latest soft updates patches for McKusick.Constantine Sapuntzakis
Integrate cleaner ffs mount code from FreeBSD. Most notably, this mount code prevents you from mounting an unclean file system read-write.
1998-10-13In vrele, vget, reinstate to following orderConstantine Sapuntzakis
- VNODE gets placed on free list - VOP_INACTIVE is called This was the original order. It was changed in an earlier patch due to a race condition in non-locking FSes (like NFS) between getnewvnode and inactive. However, the modified order had its own race conditions, so it turned out not to be a good choice.
1998-08-30Cleanup.Constantine Sapuntzakis
Error diagnostics in vputonfreelist to catch violations of assumptions.
1998-08-06Rename vop_revoke, vn_bwrite, vop_noislocked, vop_nolock, vop_nounlockConstantine Sapuntzakis
to be vop_generic_revoke, vop_generic_bwrite, vop_generic_islocked, vop_generic_lock and vop_generic_unlock. Create vop_generic_abortop and propogate change to all file systems. Fix PR/371. Get rid of locking in NULLFS (should be mostly unnecessary now except for forced unmounts).
