3119 6000 d 3 h jermar /trunk/uspace/srv/fs/fat/ Initialize in-core FAT root directory node during mount.  
3111 6000 d 21 h jermar /trunk/uspace/srv/fs/fat/ Put a frequently used construct into a function.  
3110 6000 d 22 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 6001 d 3 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 6001 d 19 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 6003 d 23 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 6004 d 3 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk  
2958 6019 d 20 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2953 6020 d 21 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 6020 d 22 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 6021 d 21 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 6021 d 21 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 6026 d 2 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 6027 d 7 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 6029 d 21 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 6029 d 23 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 6032 d 22 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 6033 d 21 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 6034 d 2 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 6034 d 5 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.
