Bruce Evans 9702cd0422 Fixed initialization of new inodes. ext2fs doesn't clear inodes when 
they are deleted, so inodes must be cleared when they are reused, but
we didn't clear the indirect blocks.  This caused serious filesystem
corruption.

Bruce Evans 0f1dddfb0c Fixed corruption of the per-group used directories count. It wasn't 
decremented when directories were removed because rev.1.12 broke the
fixup of the i_mode of the inode being removed.

Poul-Henning Kamp 987f569678 Another VFS cleanup "kilo commit" 
1.  Remove VOP_UPDATE, it is (also) an UFS/{FFS,LFS,EXT2FS,MFS}
    intereface function, and now lives in the ufsmount structure.

2.  Remove VOP_SEEK, it was unused.

3.  Add mode default vops:

    VOP_ADVLOCK          vop_einval
    VOP_CLOSE            vop_null
    VOP_FSYNC            vop_null
    VOP_IOCTL            vop_enotty
    VOP_MMAP             vop_einval
    VOP_OPEN             vop_null
    VOP_PATHCONF         vop_einval
    VOP_READLINK         vop_einval
    VOP_REALLOCBLKS      vop_eopnotsupp

    And remove identical functionality from filesystems

4.   Add vop_stdpathconf, which returns the canonical stuff.  Use
     it in the filesystems.  (XXX: It's probably wrong that specfs
     and fifofs sets this vop, shouldn't it come from the "host"
     filesystem, for instance ufs or cd9660 ?)

5.   Try to make system wide VOP functions have vop_* names.

6.   Initialize the um_* vectors in LFS.

(Recompile your LKMS!!!)

Poul-Henning Kamp cec0f20ce7 VFS mega cleanup commit (x/N) 
1.  Add new file "sys/kern/vfs_default.c" where default actions for
    VOPs go. Implement proper defaults for ABORTOP, BWRITE, LEASE,
    POLL, REVOKE and STRATEGY.  Various stuff spread over the entire
    tree belongs here.

2.  Change VOP_BLKATOFF to a normal function in cd9660.

3.  Kill VOP_BLKATOFF, VOP_TRUNCATE, VOP_VFREE, VOP_VALLOC.  These
    are private interface functions between UFS and the underlying
    storage manager layer (FFS/LFS/MFS/EXT2FS).  The functions now
    live in struct ufsmount instead.

4.  Remove a kludge of VOP_ functions in all filesystems, that did
    nothing but obscure the simplicity and break the expandability.
    If a filesystem doesn't implement VOP_FOO, it shouldn't have an
    entry for it in its vnops table.  The system will try to DTRT
    if it is not implemented.  There are still some cruft left, but
    the bulk of it is done.

5.  Fix another VCALL in vfs_cache.c (thanks Bruce!)

Poul-Henning Kamp 40715905a7 I think my previous change may have opened a race conditio. 
This patch does the same thing, with no change in semantics.

Poul-Henning Kamp 34a6a33036 ufs_ihashrem() should not be called from the UFS layer, but from the 
lower layer (LFS/FFS/?) like the rest of the ihash functions.
Otherwise it is impossible to make a lower layer that doesn't use the
ihash facility.

Bruce Evans 6789b801d1 Removed unused #includes. 1997-06-14 14:17:07 +00:00
Bruce Evans be98721964 Fixed gratuitous ANSIisms. 
Removed trailing newline from panic messages.

Bruce Evans 3c81694426 Fixed some invalid (non-atomic) accesses to `time', mostly ones of the 
form `tv = time'.  Use a new function gettime().  The current version
just forces atomicicity without fixing precision or efficiency bugs.
Simplified some related valid accesses by using the central function.

Garrett Wollman 01733a9b6d Convert QUOTA to new-style option. 1996-01-05 18:31:58 +00:00
Bruce Evans 172fc5ae28 Restored variables that are used iff QUOTA is defined. 
ext2fs still uses #if in many cases where the rest of the kernel uses
#ifdef (for QUOTA...).
