gmcgarry 284f72b8c2 Introduce NFS_DEFAULT_NIOTHREADS to define the default number
of nfs_niothreads instead of hard-coding 4.

This change has the advantage that the default can be specified
at compile time.  If the root filesystem is mounted over NFS
we don't have an opportunity to use the syscall to limit the
number of threads.  Useful on small-memory machines.

bjh21 1ca2839e35 When NFS_V2_ONLY is defined, refuse to mount NFSv3 and NQNFS filesystems,
rather than pretending they're NFSv2 and hoping for the best.  Fix based on
that supplied by Christian Groessler.

fvdl a008ea27c9 Instead of storing the filehandle in the mount structure, store the
vnode pointer. This avoids a locking problem with nfs_nget, and
can be done because we always have a reference on the root vnode
of the filesystem.

bjh21 33daa8de6b New kernel option, NFS_V2_ONLY, which aims to reduce the NFS client to just
that required to support NFSv2 mounts.  Not finished yet, but already
provides some 44k of saving in code size on arm26.  More savings, and some
documentation, are still to come.

tsarna 9bd6bb5e81 Auto-adjusting vfs.nfs.iothreads: when mounting the first nfs
filesystem, if the number of threads is "-1", meaning it's never been
set, then set it to 4.  You can override by setting this to some other
number (including 0) before or after mounting, of course.

Thanks to whoever it was that suggested this on ICB... sorry I don't
remember who.

tsarna a32696c2de Death to nfsiod!
It is replaced by kernel threads that do the same thing. The number of
kernel threads used is set with the vfs.nfs.iothreads sysctl.

jdolecek 89015c4648 Add new VFS op routine - vfs_done and call it on filesystem detach
in vfs_detach(). vfs_done may free global filesystem's resources,
typically those allocated in respective filesystem's init function.
Needed so those filesystems which went in via LKM have a chance to
clean after themselves before unloading. This fixes random panics
when LKM for filesystem using pools was loaded and unloaded several
times.

For each leaf filesystem, add appropriate vfs_done routine.

in. This code also contains the trickle syncer.

wrstuden 862a56e88b Modify vfsops to seperate vfs_fhtovp() into two routines. vfs_fhtovp() now
only handles the file handle to vnode conversion, and a new call,
vfs_checkexp(), performs the export verification.

fvdl 1cf3a3db94 * Implement optional 32 <-> 64 bit directory cookie translation. This uses
the directory cache as translation table. See nfs_subs.c for comments.
  Makes the code a bit more complex to look at than I would have liked,
  but doesn't affect the speed of the default behavior.
* Optimize caching behavior a bit when buffers are invalidated.
* Save some RPCs in readdir operations by not bothering if there is
  a small amount left to do to fill the buffer. It'll be done in the
  next RPC with a larger chunk anyway. Wastes a bit of buffer space
  but is faster.
* Make n_vattr an allocated vattr struct. This avoids nfsnode bloat,
  and is friendlier to the malloc routines.
1997-10-19 01:46:15 +00:00
fvdl 7f7d814e67 * New directory entry caching system. Provides full caching of any
directory cookie that may be thrown back at us from userspace, up
  to a size limit. Fixes double entry problem.
* Split flags for internal and external use in the NFS mount structure.
* Fix some buffer structure fields that weren're being used correctly.
* Fix missing directory cache inval call in nfs_open.
* Limit on NFS_DIRBLKSIZ no longer needed, bumped to the more reasonable
  value of 8k.
* Various other things that I forget, all related to the dir caching
  somehow, though.

From Olaf Seibert <rhialto@polder.ubc.kun.nl> (PR 3687)
* Make an attempt to check the maximum filesize before attempting
  a write to the server, as write RPCs will typically happen
  asynchronously, and the process will not see the error.
  Fixes problems with unexpectly truncated files at 4G
* Pass up errors in nfs_writerpc correctly

gwr 01adc15274 Minor reorganization of nfs_mountroot code to simplify BOOTP support.
The RPC/bootparamd calls to get the root and swap paths are now done
in nfs_boot_init() instead of nfs_boot_getfh(), so the latter now just
does the RPC/mountd call.  Also changed some panics into error returns.

cgd 90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...
