4691 5369 d 5 h svoboda /branches/dynload/ Merge trunk changes up to r4686.  
3674 5626 d 2 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
2927 5830 d 14 h decky /branches/dynload/ added dynload branch  
2766 5897 d 4 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.		  
2742 5910 d 1 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 5916 d 2 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2731 5918 d 10 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 5919 d 12 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2691 5957 d 4 h jermar /trunk/uspace/srv/vfs/ Improve the API for converting (VFS triplets, size) to VFS nodes by introducing
a new type for results of vfs_lookup_internal().		  
2687 5958 d 3 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2680 5960 d 11 h jermar /trunk/uspace/ Add basic rwlock API for uspace so that VFS can be designed/implemented using
this API. So far, the implementation of this API merely wraps futexes into
rwlocks. Real rwlocks are wanted by ticket #54.

Using the new rwlock API, replace the VFS node content futex with an rwlock.
Lock the contents rwlock as reader on reads and as writer on writes.		  
2679 5964 d 3 h jermar /trunk/uspace/srv/vfs/ Rename unlink_futex to namespace_futex and introduce a new futex for serializing
concurrent access to a VFS node's contents by multiple clients.		  
2652 5978 d 7 h jermar /trunk/uspace/srv/vfs/ VFS work.
Fix VFS node hash function to hash only within the limits of its supposed
ranges.		  
2596 6021 d 6 h jermar /trunk/uspace/srv/vfs/ VFS work.
Implement VFS node hash table management.		  
2593 6023 d 4 h jermar /trunk/uspace/srv/vfs/ A lot of more VFS prototyping.
VFS_OPEN gets reasonably complete, fix a limitation that prevented file
structures from being shared by multiple file descriptors, add functions for
file descriptor management, introduce unlink_futex and two new VFS operations
VFS_UNLINK and VFS_RENAME.		  
2590 6024 d 6 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start implementing VFS side of VFS_OPEN.
Add vfs_node.c to contain VFS node related internal functions.
