2002-01-16Don't include <sys/map.h> when you don't need what's in it.Miod Vallat

update the modification time -- required by POSIX. ok millert@ drahn@
2002-01-04Handle truncation to the middle of a file hole. deraadt@ okThomas Nordin
From FreeBSD
2001-12-19UBC was a disaster. It worked very good when it worked, but on someArtur Grabowski
machines or some configurations or in some phase of the moon (we actually don't know when or why) files disappeared. Since we've not been able to track down the problem in two weeks intense debugging and we need -current to be stable, back out everything to a state it had before UBC. We apologise for the inconvenience.
2001-12-10Big cleanup inspired by NetBSD with some parts of the code from NetBSD.Artur Grabowski
- get rid of VOP_BALLOCN and VOP_SIZE - move the generic getpages and putpages into miscfs/genfs - create a genfs_node which must be added to the top of the private portion of each vnode for filsystems that want to use genfs_{get,put}pages - rename genfs_mmap to vop_generic_mmap
2001-12-10Remove LFS crud.Artur Grabowski
2001-12-10Merge in struct uvm_vnode into struct vnode.Artur Grabowski
2001-12-05Make DEBUG not default, and make the default compileNiklas Hallqvist
2001-12-04Readd VOP_MMAP, will be used soon. Right now it's just a question toArtur Grabowski
the filesystem if we're allowed to mmap the file.
2001-12-04FREE_LOCK_INTERLOCKED drops the lock owner without changing lock "state".Artur Grabowski
ACQUIRE_LOCK_INTERLOCKED set the owner back without validating that the state is ok. This could lead to changed states and FREE_LOCK could set spl to any random value. Try to preserve the state of the lock. XXX - all this locking in the code is insane. all this debugging code breaks stuff.

2001-11-30Don't brelse a random pointer in ffs_realloccg when filesystem is fullArtur Grabowski
and bpp == NULL.
2001-11-30Fix a mergeo and don't truncate a 0 length file when freeing it.Artur Grabowski
2001-11-28Bug fixes from NetBSD.Artur Grabowski
In flush_inodedep_deps - release the lock before sleep. When allocating a pagecache dependency buffer - make sure it's always correctly initialized.
2001-11-28Bunch of bug fixes from NetBSD.Artur Grabowski
2001-11-27Merge in the unified buffer cache code as found in NetBSD 2001/03/10. TheArtur Grabowski
code is written mostly by Chuck Silvers <chuq@chuq.com>/<chs@netbsd.org>. Tested for the past few weeks by many developers, should be in a pretty stable state, but will require optimizations and additional cleanups.
2001-11-22Changes to allow two partitions to share a quota fileConstantine Sapuntzakis
2001-11-21Added sanity checksConstantine Sapuntzakis
2001-11-21Use vfs_mount_foreach_vnodeConstantine Sapuntzakis
2001-11-21Don't use #define QUOTA - use stub file insteadConstantine Sapuntzakis
Pass over the quota code in ufs/. Make code paths clearer. Clean up some names. Move all code that manipulates quotas directly into ufs_quota.c Use vfs_mount_foreach_vnode to traverse list of vnodes in mountpoint.
2001-11-15Missed one place to check for bpp == NULLArtur Grabowski
2001-11-13Allow balloc to get NULL for bpp. Don't get the buffer in that case.Artur Grabowski
2001-11-13Add two controlled panics instead of some code that I need to write later.Artur Grabowski
2001-11-13Allow the bpp arguemnt on ffs_realloccg to be NULL, don't return theArtur Grabowski
buffer in that case. Also add a new argument - blknop, which can be used to return the allocated blkno.
2001-11-06Replace inclusion of <vm/foo.h> with the correct <uvm/bar.h> when necessary.Miod Vallat
(Look ma, I might have broken the tree)

2001-09-18More cleanups from NetBSD and a bunch of endianness fixes.Artur Grabowski
The file ext2fs_bswap.c contains some functions to aid bigendian machines.
2001-09-17Some changes from NetBSD. Some cosmetic, some endianness fixes.Artur Grabowski
Plus the unwinding code that undoes allocation if a part of it fails originally from ufs and FreeBSD.

when doing sync. From FreeBSD. art@ ok.

2001-08-19More old timeouts removal, mainly affected unused/unmaintained code.Miod Vallat

2001-07-26Back out changes to symlink and mknod that were not well tested.Todd C. Miller
A simple mknod at causes a kernel panic (uvm_fault).
2001-07-26change vop_symlink and vop_mknod to return vpp (the created node)assar
refed, so that the caller can actually use it. update callers and file systems that implement these vnode operations ok'd by art
2001-07-16Make truncating a device a no-op instead of returning an error. We canConstantine Sapuntzakis
fix the rest of the kernel some other time.
2001-07-16Don't try to truncate anything except for symlinks, directories, andConstantine Sapuntzakis
regular files. ftruncate and truncate that go through FFS/EXT2FS/MFS will now return EINVAL when done on devices. Bug introduced when VOP_TRUNCATE was removed, thus removing spec_truncate. Thanks to millert@ for tracking this one down.

2001-07-05makedev is a macro. Admittedly, it's not function-like at all,Marc Espie
and should probably be spelled MAKEDEV to not trip people.

itself -- gets rid of some compilation warnings in userland. ok csapuntz@
