3111 5960 d 9 h jermar /trunk/uspace/srv/fs/fat/ Put a frequently used construct into a function.  
3110 5960 d 9 h jermar /trunk/uspace/srv/fs/fat/ Initialize global FAT IDX structures when the FAT server starts and initialize
per-file system FAT IDX structures when a file system gets mounted.		  
3109 5960 d 14 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 5961 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 5963 d 10 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 5963 d 14 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk  
2958 5979 d 7 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2953 5980 d 8 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5980 d 9 h jermar /trunk/uspace/srv/fs/fat/ Add locks to FAT index structures, FAT in-core node structures. Add futex to
protect the list of free cached FAT in-core nodes. Make fat_node_get() and
fat_node_put() and some other functions aware of these new locks.		  
2945 5981 d 8 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5981 d 8 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 5985 d 13 h jermar /trunk/uspace/srv/fs/fat/ Implement fat_node_put() and remove the node from the free node list when
bumping its refernce count from zero in fat_node_get().		  
2893 5986 d 18 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5989 d 8 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5989 d 10 h jermar /trunk/uspace/srv/fs/fat/ Need a way to locate the FAT index structure by VFS index. Also fix code that
locates the FAT index structure by position in the file system namespace.		  
2889 5992 d 9 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5993 d 9 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5993 d 13 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5993 d 17 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 6007 d 7 h jermar /trunk/uspace/srv/fs/fat/ Introduce the foundation for unique and stable FAT VFS node indices.

The first two reserved FAT entries are physically present in each FAT, so fix
the code to be aware of this.		  
2863 6007 d 18 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 6012 d 23 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 6013 d 2 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 6013 d 2 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 6013 d 3 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 6013 d 4 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 6014 d 0 h jermar /trunk/uspace/ Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.

2845 6015 d 6 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 6015 d 7 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 6015 d 8 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 6018 d 0 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 6019 d 4 h jermar /trunk/uspace/srv/fs/fat/ BPS read from FAT bootsector is little-endian. It must converted to host
endianity before being used.		  
2822 6020 d 4 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2798 6024 d 9 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 6025 d 9 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 6025 d 10 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.  
2792 6025 d 10 h jermar /trunk/uspace/ libfs' node_get() operation does not need the file system handle.  
2791 6028 d 7 h jermar /trunk/uspace/ Make libfs_lookup() more generic.  
2789 6030 d 21 h jermar /trunk/uspace/srv/fs/fat/ Fix FAT boot sector definition and introduce the FAT in-core node type.  
2770 6047 d 9 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.
