| | | | | | | | | | | | Change VM/UVM to use buf_replacevnode to change the vnode associated with a buffer. Addition v_bioflag for flags written in interrupt handlers (and read at splbio, though not strictly necessary) Add vwaitforio and use it instead of a while loop of v_numoutput. Fix race conditions when manipulation vnode free list

* New struct statfs with mount options. NOTE: this replaces statfs(2),millert1999-05-317-33/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* When vclean calls VOP_LOCK (dead_lock in this case) it has already setart1998-11-131-2/+2

* OK, this is another fix for the infamous i386 "PTDI panic". This fix is thepefo1998-08-301-2/+6
| | | | | | | | | | same as is used in 'vslock()'. The situation when this occurs is when a process tries to read or write to another process vm space and the _segment_ referenced have not yet been mapped. A certain way of crashing a system is to debug a program larger than 4 Mb (yes, those critters exist!). Set a break in an address above 4 Mb and pmap_enter panics because it can't fault in a new ptd page since it is not the process itself that calls pmap_enter. This is a fix, not a solution, but at least a user can't crash the kernel.
