3849 5604 d 22 h jermar /trunk/uspace/srv/vfs/ Allow VFS to interconnect two file system servers.  
3847 5605 d 0 h jermar /trunk/uspace/srv/vfs/ Do not close connection to VFS after a file system registers.  
3845 5605 d 13 h jermar /trunk/uspace/srv/ Nuke VFS operations structure.  
3803 5616 d 18 h decky /trunk/ configuration system overhaul (requires newt)  
3699 5654 d 1 h svoboda /trunk/uspace/ Clean .o files in individual makefiles.  
3653 5668 d 21 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3568 5690 d 1 h svoboda /trunk/uspace/ Always include Makefile.config instead of passing ARCH and COMPILER to child make on the command line. Allows running make on individual apps and allows more configuration options.  
3488 5719 d 17 h svoboda /trunk/uspace/ Fix assorted warnings.  
3352 5767 d 16 h jermar /trunk/uspace/srv/ Add reference to the mounted FS root.

This makes it possible to keep the FS root logically unlinked (i.e. lnkcnt == 0)
because it prevents VFS from attempting to destroy it during closedir().		  
3255 5781 d 2 h jermar /trunk/uspace/ Fix the VFS protocol so that the client can determine that VFS_MOUNT failed due
to a request to mount an unregistered file system.		  
3215 5813 d 23 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3201 5817 d 23 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5844 d 21 h jermar /trunk/uspace/srv/ Split the 'mount another filesystem here' and 'you are being mounted and the
device is this' mount semantics. Add VFS_MOUNTED VFS operation that corresponds
to the latter and reserve VFS_MOUNT only for the former. Because of this
change, the VFS server does not maintain the mr_node VFS node for the name space
root anymore and the VFS_LOOKUP operation is now not meant to be used on
unmounted file system, not even for looking up the root node of unmounted file
systems. In the light of these changes, TMPFS is now initialized from
tmpfs_mounted() function.		  
3079 5847 d 21 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 5863 d 14 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5863 d 16 h jermar /trunk/uspace/srv/vfs/ Cram VFS_MOUNT into one message. This creates a hidden demand for the sixth IPC
argument as there might be a desire to pass some options/flags in the future.		  
2821 5904 d 11 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2788 5915 d 4 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5931 d 16 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5932 d 14 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5932 d 16 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5933 d 16 h jermar /trunk/uspace/srv/vfs/ Grab the nodes_futex when manipulating node link counts in rename() and
_unlink().

Fix VFS futex definitions and declarations by replacing atomic_t by futex_t.		  
2763 5933 d 19 h jermar /trunk/uspace/ Support for rename().  
2753 5940 d 15 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5940 d 21 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5941 d 19 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5943 d 15 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5943 d 15 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2742 5946 d 14 h jermar /trunk/uspace/srv/ Separate creation of a TMPFS node and its linking in the file system name space.
Rename VFS_FREE to VFS_DESTROY and destroy_node() to unlink_node().		  
2740 5952 d 14 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2735 5954 d 20 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5954 d 21 h jermar /trunk/uspace/ Support for close().  
2731 5954 d 23 h jermar /trunk/uspace/srv/ Add the VFS_FREE operation. This operation frees up whatever resources used by
a file system node for which there is no name (i.e. an unlinked node).

Cleanup VFS operations enums and remove unneeded VFS operations.		  
2730 5956 d 1 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2710 5975 d 17 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 5975 d 20 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 5975 d 20 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 5975 d 21 h jermar /trunk/uspace/ Support for mkdir().  
2704 5977 d 0 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 5983 d 23 h jermar /trunk/uspace/ Introduce the notion of lflag (i.e. lookup flags) to support the ability to
limit the scope of VFS node types that can be opened by open() and opendir(). In
the future, lflag will also specify actions for VFS_LOOKUP handlers that will be
carried out in situations such as the VFS node is not found (e.g. implementation
of mkdir() and open() with O_CREAT in oflag).
