4362 5569 d 9 h jermar /trunk/uspace/srv/vfs/ Negative file descriptors shoud be considered invalid.
This fixes ticket #70.		  
4305 5587 d 14 h jermar /trunk/uspace/ Support mount options.
Let tmpfs decide whether to start empty or restored a TMPFS dump based on the mount option.		  
4302 5587 d 16 h jermar /trunk/uspace/ Make IPC_M_PING part of the VFS_MOUNT protocol again.  
4301 5587 d 16 h jermar /trunk/uspace/srv/vfs/ Return the actual error code instead of EREFUSED.  
4279 5591 d 10 h svoboda /trunk/uspace/ Nuke strncmp().  
4278 5591 d 11 h svoboda /trunk/uspace/srv/vfs/ No need for strncmp() fs_name_to_handle() as vfs_info.name is always null-terminated.  
4264 5596 d 8 h svoboda /trunk/uspace/ Nuke strcpy() and strcmp().  
4159 5616 d 9 h jermar /trunk/uspace/srv/vfs/ Just for pro forma, initialize the the link before use.  
4010 5634 d 12 h decky /trunk/uspace/srv/vfs/ support for pending (blocking) mounts (waiting for the presence of the filesystem implementation)
the mount point and filesystem type arguments of VFS_MOUNT were swapped, the IPC_M_PING was eliminated
small cleanups		  
3882 5652 d 9 h decky /trunk/uspace/ cleanup configuration
code cleanup		  
3849 5663 d 16 h jermar /trunk/uspace/srv/vfs/ Allow VFS to interconnect two file system servers.  
3847 5663 d 17 h jermar /trunk/uspace/srv/vfs/ Do not close connection to VFS after a file system registers.  
3845 5664 d 6 h jermar /trunk/uspace/srv/ Nuke VFS operations structure.  
3803 5675 d 11 h decky /trunk/ configuration system overhaul (requires newt)  
3699 5712 d 18 h svoboda /trunk/uspace/ Clean .o files in individual makefiles.  
3653 5727 d 14 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3568 5748 d 18 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 5778 d 10 h svoboda /trunk/uspace/ Fix assorted warnings.  
3352 5826 d 10 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 5839 d 20 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 5872 d 16 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3201 5876 d 16 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5903 d 14 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 5906 d 14 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 5922 d 8 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5922 d 9 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 5963 d 4 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2788 5973 d 22 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5990 d 9 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5991 d 8 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5991 d 10 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5992 d 10 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 5992 d 12 h jermar /trunk/uspace/ Support for rename().  
2753 5999 d 8 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5999 d 14 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 6000 d 12 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 6002 d 8 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 6002 d 8 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2742 6005 d 7 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 6011 d 7 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.
