4368 5570 d 11 h jermar /trunk/uspace/ Lookup a node's parent lexically rather than using the broken L_PARENT flag of
VFS_LOOKUP.		  
4366 5570 d 22 h jermar /trunk/uspace/srv/vfs/ Allow rename("a", "aa");  
4362 5572 d 22 h jermar /trunk/uspace/srv/vfs/ Negative file descriptors shoud be considered invalid.
This fixes ticket #70.		  
4305 5591 d 4 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 5591 d 6 h jermar /trunk/uspace/ Make IPC_M_PING part of the VFS_MOUNT protocol again.  
4301 5591 d 6 h jermar /trunk/uspace/srv/vfs/ Return the actual error code instead of EREFUSED.  
4279 5595 d 0 h svoboda /trunk/uspace/ Nuke strncmp().  
4278 5595 d 1 h svoboda /trunk/uspace/srv/vfs/ No need for strncmp() fs_name_to_handle() as vfs_info.name is always null-terminated.  
4264 5599 d 22 h svoboda /trunk/uspace/ Nuke strcpy() and strcmp().  
4159 5619 d 23 h jermar /trunk/uspace/srv/vfs/ Just for pro forma, initialize the the link before use.  
4010 5638 d 2 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 5655 d 23 h decky /trunk/uspace/ cleanup configuration
code cleanup		  
3849 5667 d 6 h jermar /trunk/uspace/srv/vfs/ Allow VFS to interconnect two file system servers.  
3847 5667 d 7 h jermar /trunk/uspace/srv/vfs/ Do not close connection to VFS after a file system registers.  
3845 5667 d 20 h jermar /trunk/uspace/srv/ Nuke VFS operations structure.  
3803 5679 d 1 h decky /trunk/ configuration system overhaul (requires newt)  
3699 5716 d 8 h svoboda /trunk/uspace/ Clean .o files in individual makefiles.  
3653 5731 d 4 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3568 5752 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 5782 d 0 h svoboda /trunk/uspace/ Fix assorted warnings.  
3352 5830 d 0 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 5843 d 10 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 5876 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 5880 d 6 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5907 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 5910 d 4 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 5925 d 21 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5925 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 5966 d 18 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2788 5977 d 11 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5993 d 23 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5994 d 21 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5994 d 23 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5995 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 5996 d 2 h jermar /trunk/uspace/ Support for rename().  
2753 6002 d 22 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 6003 d 4 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 6004 d 2 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 6005 d 22 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 6005 d 22 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.
