4463 5467 d 22 h decky /trunk/uspace/srv/vfs/ VFS rewrite:
- add new VFS methods
- VFS_NODE for getting VFS node for a file descriptor
- VFS_OPEN_NODE for opening an i-node directly
- VFS_DEVICE for getting the underlying device of a file (if any)
- VFS_SYNC for syncing buffers
- L_OPEN flag is set to underlying filesystem in VFS_LOOKUP when opening a file to support initialization (if any)
- VFS_CLOSE is now propagated to underlying filesystem to support cleanup (if any)		  
4445 5470 d 0 h decky /trunk/uspace/srv/vfs/ revert commit 4443 and implement a much finer solution as suggested by Jakub Jermar in commit 4444  
4443 5472 d 23 h decky /trunk/uspace/srv/vfs/ serialization of VFS_OPEN implementation to avoid lockup by concurrent open() operations from multiple tasks  
4437 5474 d 7 h jermar /trunk/uspace/srv/vfs/ Fix function definition.  
4431 5479 d 0 h jermar /trunk/uspace/srv/vfs/ Hold the namespace rwlock during the entire operation of vfs_mount_internal().
Get rid of rootfs futex, which is not needed anymore.
Do not instantiate VFS node for the mounted root if the mount failed.		  
4427 5480 d 21 h jermar /trunk/uspace/srv/vfs/ Fix rename() on a non-root file system.  
4409 5482 d 19 h jermar /trunk/uspace/ Rudimentary support for non-root mounts.  
4368 5493 d 8 h jermar /trunk/uspace/ Lookup a node's parent lexically rather than using the broken L_PARENT flag of
VFS_LOOKUP.		  
4366 5493 d 20 h jermar /trunk/uspace/srv/vfs/ Allow rename("a", "aa");  
4305 5514 d 1 h jermar /trunk/uspace/ Support mount options.
Let tmpfs decide whether to start empty or restored a TMPFS dump based on the mount option.		  
4302 5514 d 3 h jermar /trunk/uspace/ Make IPC_M_PING part of the VFS_MOUNT protocol again.  
4301 5514 d 4 h jermar /trunk/uspace/srv/vfs/ Return the actual error code instead of EREFUSED.  
4279 5517 d 22 h svoboda /trunk/uspace/ Nuke strncmp().  
4264 5522 d 20 h svoboda /trunk/uspace/ Nuke strcpy() and strcmp().  
4159 5542 d 20 h jermar /trunk/uspace/srv/vfs/ Just for pro forma, initialize the the link before use.  
4010 5560 d 23 h decky /trunk/uspace/srv/vfs/ support for pending (blocking) mounts (waiting for the presence of the filesystem implementation)
the mount point and filesystem type arguments of VFS_MOUNT were swapped, the IPC_M_PING was eliminated
small cleanups		  
3653 5654 d 1 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3488 5704 d 21 h svoboda /trunk/uspace/ Fix assorted warnings.  
3352 5752 d 21 h jermar /trunk/uspace/srv/ Add reference to the mounted FS root.

This makes it possible to keep the FS root logically unlinked (i.e. lnkcnt == 0)
because it prevents VFS from attempting to destroy it during closedir().		  
3255 5766 d 7 h jermar /trunk/uspace/ Fix the VFS protocol so that the client can determine that VFS_MOUNT failed due
to a request to mount an unregistered file system.
