4605 5616 d 5 h decky /branches/snapshot/ add task snapshoting branch  
4555 5630 d 20 h jermar /trunk/uspace/srv/vfs/ Finish converting VFS to fibril synchronization.  
4528 5635 d 23 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 5638 d 20 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 5656 d 2 h decky /trunk/uspace/srv/vfs/ avoid accessing uninitialized files array at all times  
4362 5672 d 21 h jermar /trunk/uspace/srv/vfs/ Negative file descriptors shoud be considered invalid.
This fixes ticket #70.		  
3215 5976 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().		  
2731 6117 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.		  
2683 6159 d 2 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 6202 d 0 h jermar /trunk/uspace/srv/vfs/ Add sanity checks to functions using file descriptors as indices into files.  
2593 6221 d 23 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.
