3845 5666 d 20 h jermar /trunk/uspace/srv/ Nuke VFS operations structure.  
3803 5678 d 1 h decky /trunk/ configuration system overhaul (requires newt)  
3699 5715 d 8 h svoboda /trunk/uspace/ Clean .o files in individual makefiles.  
3653 5730 d 4 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3568 5751 d 8 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 5781 d 0 h svoboda /trunk/uspace/ Fix assorted warnings.  
3352 5828 d 23 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 5842 d 9 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 5875 d 6 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3201 5879 d 6 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5906 d 4 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 5909 d 4 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 5924 d 21 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5924 d 23 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 5965 d 18 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2788 5976 d 11 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5992 d 23 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5993 d 21 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5993 d 23 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5994 d 23 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 5995 d 2 h jermar /trunk/uspace/ Support for rename().  
2753 6001 d 22 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 6002 d 4 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 6003 d 2 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 6004 d 21 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 6004 d 22 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2742 6007 d 21 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 6013 d 21 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2735 6016 d 3 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6016 d 4 h jermar /trunk/uspace/ Support for close().  
2731 6016 d 6 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 6017 d 8 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2710 6037 d 0 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 6037 d 2 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 6037 d 3 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 6037 d 4 h jermar /trunk/uspace/ Support for mkdir().  
2704 6038 d 7 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 6045 d 5 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).		  
2698 6046 d 1 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.		  
2693 6051 d 6 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.
