christos 362a4a0bd5 Yes, it was a cool trick >20 years ago to use "0123456789abcdef"[a] to
implement, xtoa(), but I think defining the samestring 50 times is a bit
too much. Defined HEXDIGITS and hexdigits in subr_prf.c and use it...

thorpej 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[].

jdolecek 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

Fixes PR kern/23835

chs 8975a0856f adjust the UBC mapping code to support non-vnode uvm_objects.
this means we can no longer look at the vnode size to determine how many
pages to request in a fault, which is good since for NFS the size can change
out from under us on the server anyway.  there's also a new flag UBC_UNMAP
for ubc_release(), so that the file system code can make the decision about
whether to cache mappings for files being used as executables.

mycroft e72fc6717e Whoops -- move the location of the VOP_OPEN()/VOP_CLOSE(), et al, from
foo_mountfs() to foo_mount(), to match the new mountroot API.
Also, for ext2fs and lfs, copy some restructuring from ffs to allow changing
file system parameters without specifying the device name.
(ntfs could use some more work.)

mycroft 0461b30ac3 Rework the mountroot interface so that vfs_mountroot() opens the root device
and just passes it on to the file system functions.  This avoids opening and
closing the device several times.

Mentioned on tech-kern some time ago, IIRC.  I've been running this for a
long time.

jdolecek 52c7db3883 change wget_utf8() to not require NUL-terminated string as input,
and adjust callers appropriately. cn_nameptr isn't NUL-terminated
for non-leaf components, so it's incorrect to assume it is always
NUL-terminated.

This fixes previous utf8-ization changes to not panic for cases
like 'echo */*/*.ps' in case the intermediate path components
are not in cache (yet).

atatat c64e485f42 Reorder ptyfs pseudo inode numbers so that 0 and 1 are unused, 2 is
the root of the file system, and slaves and masters alternate starting
at 3.  This means the inode numbers won't be really large until you
really allocate a really lot of ptys.

martin 5b98d0afc6 Declare functions with the proper type they return. While there, replace
some strange type names with their C99 equivalent.
This avoids sign extension of 32bit fields (like the file size) on 64bit
archs.
Based on a patch supplied by Olaf 'Rhialto' Seibert in PR kern/28471;
should fix that PR.

atatat f9bdf3cd08 Remove the digits() function and simply set va_bytes and va_size to
zero in ptyfs_getattr().  There's no reason to make them something
else and no other devices (except for disk devices) report anything
other than zero here, so why should we be different?

mycroft 45a21b76f0 Fixing age old cruft:
* Rather than using mnt_maxsymlinklen to indicate that a file systems returns
  d_type fields(!), add a new internal flag, IMNT_DTYPE.

Add 3 new elements to ufsmount:
* um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed
  in the first place).
* um_dirblksiz, which tracks the current directory block size, eliminating the
  FS-specific checks littered throughout the code.  This may be used later to
  make the block size variable.
* um_maxfilesize, which is the maximum file size, possibly adjusted lower due
  to implementation issues.

Sync some bug fixes from FFS into ext2fs, particularly:
* ffs_lookup.c 1.21, 1.28, 1.33, 1.48
* ffs_inode.c 1.43, 1.44, 1.45, 1.66, 1.67
* ffs_vnops.c 1.84, 1.85, 1.86

Clean up some crappy pointer frobnication.

hannken 8c21bc6224 Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
    may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
    Snapshots may not be opened for writing and the attributes are read-only.
    Use the mtime as the time this snapshot was taken.
    Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
  one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
  a vnode.
- Add snapshot support to ls, fsck_ffs and dump.
