| | | | | | | | | | | | | | | | | | systems were repo-copied from sys/miscfs to sys/fs. - Renamed the following file systems and their modules: fdesc -> fdescfs, portal -> portalfs, union -> unionfs. - Renamed corresponding kernel options: FDESC -> FDESCFS, PORTAL -> PORTALFS, UNION -> UNIONFS. - Install header files for the above file systems. - Removed bogus -I${.CURDIR}/../../sys CFLAGS from userland Makefiles.

* Add a vop_stdbmap(), and make it part of the default vop vector.Poul-Henning Kamp2001-04-291-28/+0

* Add snapshots to the fast filesystem. Most of the changes supportKirk McKusick2000-07-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | the gating of system calls that cause modifications to the underlying filesystem. The gating can be enabled by any filesystem that needs to consistently suspend operations by adding the vop_stdgetwritemount to their set of vnops. Once gating is enabled, the function vfs_write_suspend stops all new write operations to a filesystem, allows any filesystem modifying system calls already in progress to complete, then sync's the filesystem to disk and returns. The function vfs_write_resume allows the suspended write operations to begin again. Gating is not added by default for all filesystems as for SMP systems it adds two extra locks to such critical kernel paths as the write system call. Thus, gating should only be added as needed. Details on the use and current status of snapshots in FFS can be found in /sys/ufs/ffs/README.snapshot so for brevity and timelyness is not included here. Unless and until you create a snapshot file, these changes should have no effect on your system (famous last words). Notes: svn path=/head/; revision=62976

* Fixed EOF handing.Bruce Evans1997-12-131-8/+2
| | | | | | | | | | | | | | | | | | | | | 1. SS_CANTRCVMORE was initially set on the wrong socket, so reads when there has never been a writer on the socket did not return 0. Note that such reads are only possible if the fifo was opened in (O_RDONLY | O_NONBLOCK) mode. 2. SS_CANTSENDMORE was initially set on the wrong socket, but this was harmless because the wrong socket is never sent from and there is no need to set the flag initially on the right socket (since open in (O_WRONLY | O_NONBLOCK) mode fails if there is no reader...). 3. SS_CANTRCVMORE was cleared when read() returns. This broke the case where read() returns 0 - subsequent reads are supposed to return 0 until a writer appears. There is no need to clear the flag when read() returns, since it is cleared correctly when a writer appears. Notes: svn path=/head/; revision=31701

Using it here weakened the _PC_MAX_CANON, _PC_MAX_INPUT and _PC_VDISABLE cases. fifo_pathconf() is not quite correct either. _PC_CHOWN_RESTRICTED and _PC_LINK_MAX should be handled by the host file system. For directories, the host file system should let us handle _PC_PIPE_BUF. Notes: svn path=/head/; revision=31700

* Another VFS cleanup "kilo commit"Poul-Henning Kamp1997-10-161-35/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Kamp1997-10-161-8/+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

* Introduced a type `vop_t' for vnode operation functions and usedBruce Evans1995-11-092-46/+46
| | | | | | | | | | | | | | | | | | 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.
