* Introduced a type `vop_t' for vnode operation functions and usedBruce Evans1995-11-091-40/+40
| | | | | | | | | | | | | | | | | | it 1138 times (:-() in casts and a few more times in declarations. This change is null for the i386. The type has to be `typedef int vop_t(void *)' and not `typedef int vop_t()' because `gcc -Wstrict-prototypes' warns about the latter. Since vnode op functions are called with args of different (struct pointer) types, neither of these function types is any use for type checking of the arg, so it would be preferable not to use the complete function type, especially since using the complete type requires adding 1138 casts to avoid compiler warnings and another 40+ casts to reverse the function pointer conversions before calling the functions.

* These changes embody the support of the fully coherent merged VM buffer cache,David Greenman1995-01-091-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | much higher filesystem I/O performance, and much better paging performance. It represents the culmination of over 6 months of R&D. The majority of the merged VM/cache work is by John Dyson. The following highlights the most significant changes. Additionally, there are (mostly minor) changes to the various filesystem modules (nfs, msdosfs, etc) to support the new VM/buffer scheme. vfs_bio.c: Significant rewrite of most of vfs_bio to support the merged VM buffer cache scheme. The scheme is almost fully compatible with the old filesystem interface. Significant improvement in the number of opportunities for write clustering. vfs_cluster.c, vfs_subr.c Upgrade and performance enhancements in vfs layer code to support merged VM/buffer cache. Fixup of vfs_cluster to eliminate the bogus pagemove stuff. vm_object.c: Yet more improvements in the collapse code. Elimination of some windows that can cause list corruption. vm_pageout.c: Fixed it, it really works better now. Somehow in 2.0, some "enhancements" broke the code. This code has been reworked from the ground-up. vm_fault.c, vm_page.c, pmap.c, vm_object.c Support for small-block filesystems with merged VM/buffer cache scheme. pmap.c vm_map.c Dynamic kernel VM size, now we dont have to pre-allocate excessive numbers of kernel PTs. vm_glue.c Much simpler and more effective swapping code. No more gratuitous swapping. proc.h Fixed the problem that the p_lock flag was not being cleared on a fork. swap_pager.c, vnode_pager.c Removal of old vfs_bio cruft to support the past pseudo-coherency. Now the code doesn't need it anymore. machdep.c Changes to better support the parameter values for the merged VM/buffer cache scheme. machdep.c, kern_exec.c, vm_glue.c Implemented a seperate submap for temporary exec string space and another one to contain process upages. This eliminates all map fragmentation problems that previously existed. ffs_inode.c, ufs_inode.c, ufs_readwrite.c Changes for merged VM/buffer cache. Add "bypass" support for sneaking in on busy buffers. Submitted by: John Dyson and David Greenman Notes: svn path=/head/; revision=5455
* Fix panic for `cp -p' by root to an msdos file system. Improve handlingBruce Evans1994-12-271-16/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of attributes so that `cp -p' to an msdos file system can succeed under favourable circumstances (no uid or gid changes and no nonzero flags except SF_ARCHIVED). msdosfs_vnops.c: The in-core inode flags were confused with the on-disk inode flags, so chflags() clobbered the lock flag and caused a panic. denode.h, msdosfs_denode.c, msdosfs_vnops.c: Support the msdosfs archive attibute (ATTR_ARCHIVE) by mapping it to the complement of the SF_ARCHIVED flag and setting the ATTR_ARCHIVE bit when a file's modification time is set (but not when a file's permissions are set; this is the standard wrong DOS behaviour). denode.h, msdosfs_denode.c: Remove the DE_UPDAT() macro. It was only used once, and the corresponding macro in ufs has already been removed. denode.h: Don't change the timestamp for directories in DE_TIMES() (be consistent with deupdat()). msdosfs_vnops.c: Handle chown() better: return EPERM instead of EINVAL if there are insufficient permissions; otherwise, allow null changes. Notes: svn path=/head/; revision=5241
* Fix numerous timestamp bugs.Bruce Evans1994-12-121-14/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DE_UPDATE was confused with DE_MODIFIED in some places (they do have confusing names). Handle them exactly the same as IN_UPDATE and IN_MODIFIED. This fixes chmod() and chown() clobbering the mtime and other bugs. DE_MODIFIED was set but not used. Parenthesize macro args. DE_TIMES() now takes a timeval arg instead of a timespec arg. It was stupid to use a macro for speed and do unused conversions to prepare for the macro. Restore the left shifting of the DOS seconds count by 1. It got lost among the shifts for the bitfields, so DOS seconds counts appeared to range from 0 to 29 seconds (step 1) instead of 0 to 58 seconds (step 2). Actually use the passed-in mtime in deupdat() as documented so that utimes() works. Change `extern __inline's to `static inline's so that msdosfs_fat.o can be linked when it is compiled without -O. Remove faking of directory mtimes to always be the current time. It's more surprising for directory mtimes to change when you read the directories than for them not to change when you write the directories. This should be controlled by a mount-time option if at all. Notes: svn path=/head/; revision=5083
