3521 5852 d 13 h jermar /trunk/uspace/ Move libfs_blockread(), block_get() and block_put() to libblock.  
3352 5918 d 10 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 5933 d 9 h jermar /trunk/uspace/ Add a comment to libfs_blockread() and change type from size_t to off_t at
various places.
 
3251 5933 d 11 h jermar /trunk/uspace/ Move tmpfs_blockread() to libfs and rename it to libfs_blockread().
Add one argument to specify block size.
 
3250 5933 d 12 h jermar /trunk/uspace/srv/fs/tmpfs/ Let tmpfs_blockread() use async_req_2_1() instead of ipc_call_sync_2_1().  
3247 5934 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ Avoid magic numbers in tmpfs_dump.c.  
3201 5968 d 17 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5995 d 15 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 5996 d 7 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 5998 d 11 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 5998 d 15 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk  
2958 6014 d 8 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2863 6042 d 19 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.
 
2858 6048 d 3 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.
 
2857 6048 d 3 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2852 6049 d 1 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 6050 d 7 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2831 6053 d 1 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2792 6060 d 10 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 6063 d 7 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2770 6082 d 9 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2763 6084 d 13 h jermar /trunk/uspace/ Support for rename().  
2760 6087 d 7 h jermar /trunk/uspace/ Support for multiple TMPFS node names.  
2758 6088 d 8 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 6088 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Set the TMPFS root node's link count to 1.  
2756 6088 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Introduce real link counts for TMPFS.  
2747 6095 d 7 h jermar /trunk/uspace/ Move the core lookup logic from TMPFS to libfs.  
2742 6097 d 8 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 6103 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Remove duplicate initialization.  
2736 6105 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 6105 d 14 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 6105 d 15 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 6105 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 6105 d 16 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 6106 d 18 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6111 d 8 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6126 d 11 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 6126 d 11 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 6126 d 15 h jermar /trunk/uspace/ Support for mkdir().  
2706 6126 d 19 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
