| | | | | | | | | | | | | | | dishonored in rev.1.1 by commenting out the code that honored it. This gave the worst disadvantages of async mounts in an uncontrollable way. Honoring the flag costs about 50% in real time in worst cases on a new but not very fast ATA drive with write caching (probably more on drives without write caching). The old misbehavior can be recovered using async mounts after implementing them in mount_ext2fs(8) (just put the MNT_ASYNC flag in mount_ext2fs's table of supported options like it is in mount's table).

* Regularize the vop_stdlock'ing protocol across all the filesystemsKirk McKusick2002-10-141-1/+0
| | | | | | | | | | | | | | | | | | | | | | | that use it. Specifically, vop_stdlock uses the lock pointed to by vp->v_vnlock. By default, getnewvnode sets up vp->v_vnlock to reference vp->v_lock. Filesystems that wish to use the default do not need to allocate a lock at the front of their node structure (as some still did) or do a lockinit. They can simply start using vn_lock/VOP_UNLOCK. Filesystems that wish to manage their own locks, but still use the vop_stdlock functions (such as nullfs) can simply replace vp->v_vnlock with a pointer to the lock that they wish to have used for the vnode. Such filesystems are responsible for setting the vp->v_vnlock back to the default in their vop_reclaim routine (e.g., vp->v_vnlock = &vp->v_lock). In theory, this set of changes cleans up the existing filesystem lock interface and should have no function change to the existing locking scheme. Sponsored by: DARPA & NAI Labs.

Originally it may have made sense to share common features between the two filesystems, but recently it has only caused problems, the UFS2 work being the final straw.

* Remove B_READ, B_WRITE and B_FREEBUF and replace them with a newPoul-Henning Kamp2000-03-201-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | field in struct buf: b_iocmd. The b_iocmd is enforced to have exactly one bit set. B_WRITE was bogusly defined as zero giving rise to obvious coding mistakes. Also eliminate the redundant struct buf flag B_CALL, it can just as efficiently be done by comparing b_iodone to NULL. Should you get a panic or drop into the debugger, complaining about "b_iocmd", don't continue. It is likely to write on your disk where it should have been reading. This change is a step in the direction towards a stackable BIO capability. A lot of this patch were machine generated (Thanks to style(9) compliance!)

UFS_LAZYMOD is intentionally left out of /sys/conf/options. This is mainly to avoid almost useless disk i/o on battery powered machines. It's silly to write to disk (on the next sync or when the inode becomes inactive) just because someone hit a key or something wrote to the screen or /dev/null.

* Eradicate the variable "time" from the kernel, using various measures.Poul-Henning Kamp1998-03-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "time" wasn't a atomic variable, so splfoo() protection were needed around any access to it, unless you just wanted the seconds part. Most uses of time.tv_sec now uses the new variable time_second instead. gettime() changed to getmicrotime(0. Remove a couple of unneeded splfoo() protections, the new getmicrotime() is atomic, (until Bruce sets a breakpoint in it). A couple of places needed random data, so use read_random() instead of mucking about with time which isn't random. Add a new nfs_curusec() function. Mark a couple of bogosities involving the now disappeard time variable. Update ffs_update() to avoid the weird "== &time" checks, by fixing the one remaining call that passwd &time as args. Change profiling in ncr.c to use ticks instead of time. Resolution is the same. Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call hzto() which subtracts time" sequences.

Remove VOP_SEEK, it was unused. 3.

(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.

* VFS mega cleanup commit (x/N)Poul-Henning Kamp1997-10-161-16/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | 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
