Use positive, not negative logic.

Do not blindly pass linux filesystem specific mount data across.

Ignore MNT_NODEV option, it is implicit in choice of filesystem.

Changes to MI Linux emulation code necessary to run 32-bit Linux binaries

2004-08-16T07:28:16+00:00

on AMD64, and the general case where the emulated platform has different
size pointers than we use natively:
- declare certain structure members as l_uintptr_t and use the new PTRIN
  and PTROUT macros to convert to and from native pointers.
- declare some structures __packed on amd64 when the layout would differ
  from that used on i386.
- include  instead of 
  if compiling with COMPAT_LINUX32. This will need to be revisited before
  32-bit and 64-bit Linux emulation support can coexist in the same kernel.
- other small scattered changes.

This should be a no-op on i386 and Alpha.

Use kernel_vmount() instead of vfs_nmount().

2004-07-27T21:38:42+00:00

Use vfs_nmount() to mount linprocfs filesystems in linux_mount();

2004-03-16T09:05:56+00:00

linprocfs doesn't support the old mount interface.

Correct size argument passed to copyinstr() in linux_mount(): mntfromname

2004-03-16T08:37:19+00:00

and mntonname are both MNAMELEN characters long, not MFSNAMELEN.

Do not call VOP_GETATTR in getdents function. It does not serve any

purpose and the resulting vattr structure was ignored. In addition,
the VOP_GETATTR call was made with no vnode lock held, resulting in
vnode locking violation panic with debug kernels.

Add a f_vnode field to struct file.

2003-06-22T08:41:43+00:00

Several of the subtypes have an associated vnode which is used for
stuff like the f*() functions.

By giving the vnode a speparate field, a number of checks for the specific
subtype can be replaced simply with a check for f_vnode != NULL, and
we can later free f_data up to subtype specific use.

At this point in time, f_data still points to the vnode, so any code I
might have overlooked will still work.
