3665 5825 d 19 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3343 5931 d 1 h decky /branches/sparc/ add sparc branch  
3215 5974 d 5 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3109 6005 d 3 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 6008 d 3 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2821 6064 d 17 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2770 6091 d 22 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2766 6093 d 22 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 6094 d 1 h jermar /trunk/uspace/ Support for rename().  
2752 6101 d 3 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2742 6106 d 20 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().		  
2735 6115 d 2 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6115 d 3 h jermar /trunk/uspace/ Support for close().  
2731 6115 d 5 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 6116 d 7 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2709 6136 d 2 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2707 6136 d 3 h jermar /trunk/uspace/ Support for mkdir().  
2704 6137 d 6 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 6144 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).		  
2693 6150 d 5 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.
