4585 5612 d 8 h jermar /trunk/uspace/ Introduce VFS_IN_FSTAT and VFS_OUT_STAT.
Provide libc fstat() and devfs_stat().
This functionality replaces VFS_IN_NODE
and VFS_IN/OUT_DEVICE. FAT and TMPFS
still do not implement this and VFS_IN_STAT
and stat() need implementation as well.		  
4566 5615 d 6 h jermar /trunk/uspace/srv/vfs/ Do not use the "pending" fibril mechanism in VFS  
4555 5623 d 5 h jermar /trunk/uspace/srv/vfs/ Finish converting VFS to fibril synchronization.  
4539 5625 d 8 h jermar /trunk/uspace/srv/vfs/ Handle pending mounts using only one fibril.  
4518 5631 d 5 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.		  
4509 5632 d 14 h decky /trunk/uspace/ rename libadt -> adt  
4463 5637 d 8 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)		  
4401 5653 d 8 h svoboda /trunk/uspace/ C binding for devmap. Gets rid of duplicate code.  
4368 5662 d 19 h jermar /trunk/uspace/ Lookup a node's parent lexically rather than using the broken L_PARENT flag of
VFS_LOOKUP.		  
4305 5683 d 12 h jermar /trunk/uspace/ Support mount options.
Let tmpfs decide whether to start empty or restored a TMPFS dump based on the mount option.		  
4010 5730 d 10 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		  
3845 5760 d 4 h jermar /trunk/uspace/srv/ Nuke VFS operations structure.  
3653 5823 d 12 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3215 5968 d 14 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3109 5999 d 12 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 6002 d 12 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2821 6059 d 2 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2770 6086 d 7 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2766 6088 d 7 h jermar /trunk/uspace/srv/vfs/ Grab the nodes_futex when manipulating node link counts in rename() and
_unlink().

Fix VFS futex definitions and declarations by replacing atomic_t by futex_t.		  
2763 6088 d 10 h jermar /trunk/uspace/ Support for rename().
