3847 5581 d 13 h jermar /trunk/uspace/srv/vfs/ Do not close connection to VFS after a file system registers.  
3845 5582 d 2 h jermar /trunk/uspace/srv/ Nuke VFS operations structure.  
3803 5593 d 7 h decky /trunk/ configuration system overhaul (requires newt)  
3699 5630 d 14 h svoboda /trunk/uspace/ Clean .o files in individual makefiles.  
3653 5645 d 10 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3568 5666 d 14 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 5696 d 6 h svoboda /trunk/uspace/ Fix assorted warnings.  
3352 5744 d 6 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 5757 d 16 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 5790 d 12 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3201 5794 d 12 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5821 d 10 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 5824 d 10 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 5840 d 3 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5840 d 5 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 5881 d 0 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2788 5891 d 18 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5908 d 5 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5909 d 3 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5909 d 5 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5910 d 5 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 5910 d 8 h jermar /trunk/uspace/ Support for rename().  
2753 5917 d 4 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5917 d 10 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5918 d 8 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5920 d 4 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5920 d 4 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2742 5923 d 3 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 5929 d 3 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2735 5931 d 9 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5931 d 11 h jermar /trunk/uspace/ Support for close().  
2731 5931 d 12 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 5932 d 14 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2710 5952 d 7 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 5952 d 9 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 5952 d 9 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 5952 d 10 h jermar /trunk/uspace/ Support for mkdir().  
2704 5953 d 13 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 5960 d 12 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 5961 d 7 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
