4718 5350 d 15 h mejdrech /branches/network/ Net: merge with trunk head (0.4.1)  
4581 5443 d 9 h mejdrech /branches/network/ Net: synchronized with trunk rev.4580  
4153 5544 d 8 h mejdrech /branches/network/ Networking: merged with trunk changes  
3386 5740 d 11 h decky /branches/network/ add new network branch (copy of current trunk)  
2766 5918 d 8 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 5931 d 5 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 5937 d 6 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2731 5939 d 14 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 5940 d 16 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2691 5978 d 8 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 5979 d 7 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2680 5981 d 15 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 5985 d 7 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 5999 d 11 h jermar /trunk/uspace/srv/vfs/ VFS work.
Fix VFS node hash function to hash only within the limits of its supposed
ranges.		  
2596 6042 d 10 h jermar /trunk/uspace/srv/vfs/ VFS work.
Implement VFS node hash table management.		  
2593 6044 d 8 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 6045 d 10 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.
