4555	5670 d 9 h	jermar	/trunk/uspace/srv/vfs/	Finish converting VFS to fibril synchronization.
4528	5675 d 12 h	svoboda	/trunk/uspace/	Use 'fibril_local' modifier for fibril-local variables instead of '__thread'. Since it is decalred in fibril.h, it need not begin with '__'.
4518	5678 d 10 h	jermar	/trunk/uspace/srv/vfs/	Make VFS use the new synchronization for fibrils. Now there should be no (or only secondary) fibril serialization. Code reorganized not to hold the phone lock during async_wait_for() in most cases. Tested on ia32. On amd64, VFS crashes, but I think it is an unrelated problem.
4432	5695 d 16 h	decky	/trunk/uspace/srv/vfs/	avoid accessing uninitialized files array at all times
4362	5712 d 11 h	jermar	/trunk/uspace/srv/vfs/	Negative file descriptors shoud be considered invalid. This fixes ticket #70.
3215	6015 d 19 h	jermar	/trunk/uspace/srv/vfs/	Instead of aborting or crashing, return EBADF when an invalid file descriptor is passed to vfs_close().
2731	6156 d 19 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.
2683	6198 d 15 h	jermar	/trunk/uspace/srv/vfs/	Introduce the open file lock. Modify vfs_rdwr() to take this lock into account when reading or writing from/to an open file.
2624	6241 d 13 h	jermar	/trunk/uspace/srv/vfs/	Add sanity checks to functions using file descriptors as indices into files.
2593	6261 d 12 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.
