3352 5784 d 13 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().
 
3252 5799 d 12 h jermar /trunk/uspace/ Add a comment to libfs_blockread() and change type from size_t to off_t at
various places.
 
3251 5799 d 14 h jermar /trunk/uspace/ Move tmpfs_blockread() to libfs and rename it to libfs_blockread().
Add one argument to specify block size.
 
3250 5799 d 15 h jermar /trunk/uspace/srv/fs/tmpfs/ Let tmpfs_blockread() use async_req_2_1() instead of ipc_call_sync_2_1().  
3247 5800 d 15 h jermar /trunk/uspace/srv/fs/tmpfs/ Avoid magic numbers in tmpfs_dump.c.  
3201 5834 d 20 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5861 d 18 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.
 
3103 5862 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Evict the code which loads the TMPFS file system from a file system dump to a
dedicated source file.
 
3091 5864 d 14 h jermar /trunk/uspace/srv/fs/tmpfs/ Return value argument to ipc_call_sync_X_Y() may not be int or it will
break on 64-machines that are sensitive to unaligned memory accesses.
Moreover, overcasting int * to sysarg_t * is not a good idea either
even if the int is by chance aligned on a 64-bit boundary as some
unknown memory will get overwritten during the assignment. Change the
type of the retval argument to ipcarg_t.
 
3087 5864 d 18 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk  
2958 5880 d 11 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2863 5908 d 22 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.
 
2858 5914 d 6 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.
 
2857 5914 d 6 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2852 5915 d 4 h jermar /trunk/uspace/ Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
 
2844 5916 d 11 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2831 5919 d 4 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2792 5926 d 13 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 5929 d 11 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2770 5948 d 13 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 5950 d 16 h jermar /trunk/uspace/ Support for rename().  
2760 5953 d 11 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 5954 d 11 h jermar /trunk/uspace/ No need to keep the parent pointer in the TMPFS node. Moreover, other file
systems won't have it either. Finally, if TMPFS is to support hardlinks, there
can be multiple parents.
 
2757 5954 d 13 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 5954 d 13 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 5961 d 10 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 5963 d 11 h jermar /trunk/uspace/srv/ Separate creation of a TMPFS node and its linking in the file system name space.
Rename VFS_FREE to VFS_DESTROY and destroy_node() to unlink_node().
 
2739 5969 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 5971 d 13 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5971 d 17 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 5971 d 19 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5971 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 5971 d 20 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.
 
2730 5972 d 22 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 5977 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 5992 d 14 h jermar /trunk/uspace/ Remove the debugging hack from tmpfs_init(), which created several files and
directories on the filesystem. TMPFS is now self-sufficient enough to be able
to create its content via the standard VFS interface.
 
2710 5992 d 14 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 5992 d 18 h jermar /trunk/uspace/ Support for mkdir().  
2706 5992 d 22 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 5993 d 11 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.
