* Lock reporting and assertion changes.Eivind Eklund1999-12-111-1/+6
| | | | | | | | | | | | | | | | | | * lockstatus() and VOP_ISLOCKED() gets a new process argument and a new return value: LK_EXCLOTHER, when the lock is held exclusively by another process. * The ASSERT_VOP_(UN)LOCKED family is extended to use what this gives them * Extend the vnode_if.src format to allow more exact specification than locked/unlocked. This commit should not do any semantic changes unless you are using DEBUG_VFS_LOCKS. Discussed with: grog, mch, peter, phk Reviewed by: peter Notes: svn path=/head/; revision=54444

* In the words of the submitter:Mike Smith1998-05-071-20/+20
| | | | | | | | | | | | | | | | | | | | | | --------- Make callers of namei() responsible for releasing references or locks instead of having the underlying filesystems do it. This eliminates redundancy in all terminal filesystems and makes it possible for stacked transport layers such as umapfs or nullfs to operate correctly. Quality testing was done with testvn, and lat_fs from the lmbench suite. Some NFS client testing courtesy of Patrik Kudo. vop_mknod and vop_symlink still release the returned vpp. vop_rename still releases 4 vnode arguments before it returns. These remaining cases will be corrected in the next set of patches. --------- Submitted by: Michael Hancock <michaelh@cet.co.jp> Notes: svn path=/head/; revision=35823

* Another VFS cleanup "kilo commit"Poul-Henning Kamp1997-10-161-22/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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!!!) Notes: svn path=/head/; revision=30492
* VFS mega cleanup commit (x/N)Poul-Henning Kamp1997-10-161-41/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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!) Notes: svn path=/head/; revision=30474

This bug is seen when doing "ln /dev/console /dev/foo" or equivilent and first appeared after I fixed the argument order of VOP_LINK. YUCK! There really needs to be a way of specifying what vp to use in the VCALL; doing this could fix the strategy and bwrite special-cases, too. Notes: svn path=/head/; revision=9430
