2ddaf8b92b Nodes cannot use the '0' identifier or they will be skipped by readdir. 
E.g., the root node's '.' and '..' directory entries did not appear in
a directory list, because the root node always holds the first id.

a12024da06 Use nanotime() to update the time fields in filesystems. Convert the code 
from macros to real functions. Original patch and review from chuq.
Note: ext2fs only keeps seconds in the on-disk inode, and msdosfs does not
have enough precision for all fields, so this is not very useful for those
two.

ec93365612 Initial addition of tmpfs, an efficient memory file-system. This project 
was developed as part of Google's Summer of Code 2005 program.  This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.

The file-system is still *experimental*.  Therefore, it is disabled by
default in all kernels.  However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.

OK'ed by my project mentor, William Studenmund (wrstuden@).

529eaccb6b The maximum file size on MS-DOS filesystems is 4 GB - 1 byte, so 
don't bother trying to write files bigger than this.  Just return
EFBIG to caller, rather than panic()ing later.

From OpenBSD.

This closes my PR kern/30864: "panic when copying files of >4GB on msdosfs"

d8c6d7b24e statvfs(2) returns bogus result from union mounted file systems with 
`-r' option, since it uses uninitialized buffer in the case of no
lower-layer file system.

So, add M_ZERO to malloc(9) flags to initialize the buffer.

df13e3579e Change the rest of the sysctl subsystem to use const consistently. 
The __UNCONST macro is now used only where necessary and the RW macros
are gone.  Most of the changes here are consumers of the
sysctl_createv(9) interface that now takes a pair of const pointers
which used not to be.

e633e8b61b - Define a VFS_ATTACH() macro that places a reference to a vfsops structure 
into the "vfsops" link set.
- Use VFS_ATTACH() where vfsops are declared for individual file systems.
- In vfsinit(), traverse the "vfsops" link set, rather than vfs_list_initial[].

877dee10ba read always single cluster of data, to avoid confusing the buffer 
cache; this appears to fix the random file content corruption which
happens when more than one cluster is read at the same time, i.e. for
files > 3*cluster_size
