4463 5555 d 19 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 5557 d 21 h decky /trunk/uspace/srv/vfs/ revert commit 4443 and implement a much finer solution as suggested by Jakub Jermar in commit 4444  
4444 5560 d 19 h jermar /trunk/uspace/srv/vfs/ Put a comment for consideration.  
4443 5560 d 20 h decky /trunk/uspace/srv/vfs/ serialization of VFS_OPEN implementation to avoid lockup by concurrent open() operations from multiple tasks  
4437 5562 d 5 h jermar /trunk/uspace/srv/vfs/ Fix function definition.  
4432 5566 d 22 h decky /trunk/uspace/srv/vfs/ avoid accessing uninitialized files array at all times  
4431 5566 d 22 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 5568 d 19 h jermar /trunk/uspace/srv/vfs/ Fix rename() on a non-root file system.  
4413 5570 d 2 h decky /trunk/uspace/ add space before $@  
4409 5570 d 17 h jermar /trunk/uspace/ Rudimentary support for non-root mounts.  
4406 5570 d 17 h jermar /trunk/uspace/srv/vfs/ Remove unused and non-functional code.  
4401 5571 d 19 h svoboda /trunk/uspace/ C binding for devmap. Gets rid of duplicate code.  
4368 5581 d 6 h jermar /trunk/uspace/ Lookup a node's parent lexically rather than using the broken L_PARENT flag of
VFS_LOOKUP.		  
4366 5581 d 17 h jermar /trunk/uspace/srv/vfs/ Allow rename("a", "aa");  
4362 5583 d 17 h jermar /trunk/uspace/srv/vfs/ Negative file descriptors shoud be considered invalid.
This fixes ticket #70.		  
4305 5601 d 23 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 5602 d 1 h jermar /trunk/uspace/ Make IPC_M_PING part of the VFS_MOUNT protocol again.  
4301 5602 d 1 h jermar /trunk/uspace/srv/vfs/ Return the actual error code instead of EREFUSED.  
4279 5605 d 19 h svoboda /trunk/uspace/ Nuke strncmp().  
4278 5605 d 20 h svoboda /trunk/uspace/srv/vfs/ No need for strncmp() fs_name_to_handle() as vfs_info.name is always null-terminated.  
4264 5610 d 17 h svoboda /trunk/uspace/ Nuke strcpy() and strcmp().  
4159 5630 d 18 h jermar /trunk/uspace/srv/vfs/ Just for pro forma, initialize the the link before use.  
4010 5648 d 21 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		  
3882 5666 d 18 h decky /trunk/uspace/ cleanup configuration
code cleanup		  
3849 5678 d 1 h jermar /trunk/uspace/srv/vfs/ Allow VFS to interconnect two file system servers.  
3847 5678 d 2 h jermar /trunk/uspace/srv/vfs/ Do not close connection to VFS after a file system registers.  
3845 5678 d 15 h jermar /trunk/uspace/srv/ Nuke VFS operations structure.  
3803 5689 d 20 h decky /trunk/ configuration system overhaul (requires newt)  
3699 5727 d 3 h svoboda /trunk/uspace/ Clean .o files in individual makefiles.  
3653 5741 d 23 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3568 5763 d 3 h svoboda /trunk/uspace/ Always include Makefile.config instead of passing ARCH and COMPILER to child make on the command line. Allows running make on individual apps and allows more configuration options.  
3488 5792 d 19 h svoboda /trunk/uspace/ Fix assorted warnings.  
3352 5840 d 19 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 5854 d 5 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.		  
3215 5887 d 1 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3201 5891 d 1 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5917 d 23 h jermar /trunk/uspace/srv/ Split the 'mount another filesystem here' and 'you are being mounted and the
device is this' mount semantics. Add VFS_MOUNTED VFS operation that corresponds
to the latter and reserve VFS_MOUNT only for the former. Because of this
change, the VFS server does not maintain the mr_node VFS node for the name space
root anymore and the VFS_LOOKUP operation is now not meant to be used on
unmounted file system, not even for looking up the root node of unmounted file
systems. In the light of these changes, TMPFS is now initialized from
tmpfs_mounted() function.		  
3079 5920 d 23 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 5936 d 16 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5936 d 18 h jermar /trunk/uspace/srv/vfs/ Cram VFS_MOUNT into one message. This creates a hidden demand for the sixth IPC
argument as there might be a desire to pass some options/flags in the future.
