pooka fbc9efbb6a Do fhtovp compat translation only for fhtovp ops, not all vfs ops. 
Allocate tailing extra buffer for compat op too.

hannken 7296ba383a Replace vget() with vref()/vn_lock(), this node already has a reference. 2010-07-09 08:10:50 +00:00

calls.

several years without doing anything useful.

a server which runs in 32bit time_t namespace.

pooka 013ecf4f81 Make sure that pa_spare is zero-filled and does not contain any 
garbage which might disrupt future use.

pooka e73db95236 union doesn't use layerfs (avoids panic in kernel bootstrap when 
union is compiled in but none of the layer-using file systems are).

hannken c2de422c87 LK_INTERLOCK is no longer a valid flag for VOP_LOCK(). 2010-07-02 07:56:46 +00:00
rmind 71cf548ad1 tmpfs_lookup: add comment, de-ident main path. No functional change. 
tmpfs_dir_attach: add assert.

hannken 245651a23d Remove vlockmgr(). Generic vnode lock operations now use a rwlock located 
in the vnode.  All LK_* flags move from sys/lock.h to sys/vnode.h.  Calls
to vlockmgr() in file systems get replaced with VOP_LOCK() or VOP_UNLOCK().

Welcome to 5.99.34.

Discussed on tech-kern.

hannken e65a328302 The directory vnode must be locked before we call VOP_WHITEOUT(). 
Should fix PR #23986 "problem mounting directories".

rmind 559464716e tmpfs_bytes_max: use MIN() rather than min(), which returns int. 
Spotted by Wolfgang Solfrank.

rmind bf5767dcea tmpfs_statvfs: hold accounting lock, since tmpfs_pages_avail() and 
tmpfs_bytes_max() may fluctuate while in calculations.

reinoud cd63900e30 Pullup changes from the write implementation:

  images. A field has been added in the segment summary.

hannken f6c438ba23 Clean up vnode lock operations: 
- VOP_LOCK(vp, flags): Limit the set of allowed flags to LK_EXCLUSIVE,
   LK_SHARED and LK_NOWAIT.  LK_INTERLOCK is no longer allowed as it
   makes no sense here.

- VOP_ISLOCKED(vp): Remove the for some time unused return value
  LK_EXCLOTHER.  Mark this operation as "diagnostic only".
  Making a lock decision based on this operation is no longer allowed.

rmind fc8b3b7154 Replace tmpfs_pool custom allocator code with a simpler layer for memory 
accounting.  Use wired memory (which can be limited) for meta-data, and
kmem(9) for string allocations.

Close PR/31944.  Fix PR/38361 while here.  OK ad@.

pooka a784ae74af Make retval argument for pathconf a register_t to match VOP_PATHCONF. 
This makes the size the same on 64bit archs.  Don't bother bumping
any version, since you'd have explicitly had to jump through some
hoops to use pathconf before.

hannken 62bfdd2b21 Change layered file systems to always pass the locking VOP's down to the 
leaf file system.  Remove now unused member v_vnlock from struct vnode.

pooka 704f8889fa Mark files removed in the in-memory structure. This allows us 
to do two things:

 1) properly set "recycle?" in inactive
 2) easily check if we are renaming a removed vnode.  without the
    check, it was possible to enter a dirent in the file system for
    a removed (and hence scheduled to be vcleaned) vnode.  this would
    lead to the succesful vget() of a clean vnode.  the use of the
    cleaned vnode was, however, less succesful, except for purposes
    of crashing.

pooka 19264c8c5c Initialize *vpp to NULL: relookup() requires it without initializing 
the value before the call (yea, changing relookup would probably
be smart, but other file systems already initialize vpp, so I'm
letting someone else experiment with tylenol od).

number and not on their timestamp since one of the timestamps could be wrong when the

pooka eb097b1b96 Return correct value from union_islocked. 
(XXX: anything asserting LK_SHARED will fail because union doesn't
support shared locks)

pooka 0c20c076ce Enforce RLIMIT_FSIZE before VOP_WRITE. This adds support to file 
system drivers where it was missing from and fixes one buggy
implementation.  The arguably weird semantics of the check are
maintained (v_size vs. va_bytes, overwrite).
