4463 5597 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 5600 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  
4444 5602 d 22 h jermar /trunk/uspace/srv/vfs/ Put a comment for consideration.  
4443 5602 d 23 h decky /trunk/uspace/srv/vfs/ serialization of VFS_OPEN implementation to avoid lockup by concurrent open() operations from multiple tasks  
4437 5604 d 7 h jermar /trunk/uspace/srv/vfs/ Fix function definition.  
4432 5609 d 1 h decky /trunk/uspace/srv/vfs/ avoid accessing uninitialized files array at all times  
4431 5609 d 1 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 5610 d 22 h jermar /trunk/uspace/srv/vfs/ Fix rename() on a non-root file system.  
4413 5612 d 5 h decky /trunk/uspace/ add space before $@  
4409 5612 d 19 h jermar /trunk/uspace/ Rudimentary support for non-root mounts.  
4406 5612 d 20 h jermar /trunk/uspace/srv/vfs/ Remove unused and non-functional code.  
4401 5613 d 22 h svoboda /trunk/uspace/ C binding for devmap. Gets rid of duplicate code.  
4368 5623 d 9 h jermar /trunk/uspace/ Lookup a node's parent lexically rather than using the broken L_PARENT flag of
VFS_LOOKUP.		  
4366 5623 d 20 h jermar /trunk/uspace/srv/vfs/ Allow rename("a", "aa");  
4362 5625 d 20 h jermar /trunk/uspace/srv/vfs/ Negative file descriptors shoud be considered invalid.
This fixes ticket #70.		  
4305 5644 d 2 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 5644 d 4 h jermar /trunk/uspace/ Make IPC_M_PING part of the VFS_MOUNT protocol again.  
4301 5644 d 4 h jermar /trunk/uspace/srv/vfs/ Return the actual error code instead of EREFUSED.  
4279 5647 d 22 h svoboda /trunk/uspace/ Nuke strncmp().  
4278 5647 d 23 h svoboda /trunk/uspace/srv/vfs/ No need for strncmp() fs_name_to_handle() as vfs_info.name is always null-terminated.  
4264 5652 d 20 h svoboda /trunk/uspace/ Nuke strcpy() and strcmp().  
4159 5672 d 20 h jermar /trunk/uspace/srv/vfs/ Just for pro forma, initialize the the link before use.  
4010 5691 d 0 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 5708 d 21 h decky /trunk/uspace/ cleanup configuration
code cleanup		  
3849 5720 d 3 h jermar /trunk/uspace/srv/vfs/ Allow VFS to interconnect two file system servers.  
3847 5720 d 5 h jermar /trunk/uspace/srv/vfs/ Do not close connection to VFS after a file system registers.  
3845 5720 d 18 h jermar /trunk/uspace/srv/ Nuke VFS operations structure.  
3803 5731 d 23 h decky /trunk/ configuration system overhaul (requires newt)  
3699 5769 d 6 h svoboda /trunk/uspace/ Clean .o files in individual makefiles.  
3653 5784 d 2 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3568 5805 d 6 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 5834 d 22 h svoboda /trunk/uspace/ Fix assorted warnings.  
3352 5882 d 22 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 5896 d 8 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 5929 d 4 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3201 5933 d 4 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5960 d 2 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 5963 d 2 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 5978 d 19 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5978 d 21 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.
