3505 5728 d 19 h jermar /trunk/uspace/srv/fs/fat/ Move functionality related to FAT dentries to fat_dentry.c.  
3504 5728 d 19 h jermar /trunk/uspace/srv/fs/fat/ Prepare to break fat_ops.c into multiple files.  
3503 5728 d 20 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_alloc_clusters().  
3501 5729 d 12 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_fill_gap().  
3500 5729 d 14 h jermar /trunk/uspace/srv/fs/fat/ More complete prototype of fat_write().  
3499 5729 d 17 h jermar /trunk/uspace/srv/fs/fat/ Mark progress in fat_write().  
3497 5729 d 21 h jermar /trunk/uspace/srv/fs/fat/ Dummy fat_write().  
3352 5793 d 12 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().		  
3335 5797 d 10 h jermar /trunk/uspace/srv/fs/fat/ Support for readdir() on FAT.  
3325 5800 d 12 h jermar /trunk/uspace/srv/fs/fat/ Determine the size of a directory node by walking the FAT and counting clusters.
This eliminates the hardcoded limit on the number of directory entries.		  
3314 5801 d 12 h jermar /trunk/uspace/srv/fs/fat/ fat_read() should expect IPC_M_DATA_READ instead of IPC_M_DATA_WRITE.  
3312 5801 d 12 h jermar /trunk/uspace/srv/fs/fat/ When removing a FAT node from the ffn list, use the correct pointer instead of
an uninitialized one.		  
3308 5803 d 11 h jermar /trunk/uspace/srv/fs/fat/ More complete fat_read().  
3307 5803 d 12 h jermar /trunk/uspace/srv/fs/fat/ Dummy implementation of fat_read().  
3282 5805 d 9 h jermar /trunk/uspace/srv/fs/fat/ FAT dentry type used for subdirectories doesn't store the directory size in the 'size' field.
Introduce a simple workaround that will let us have 64 directory entries at maximum.		  
3272 5805 d 22 h jermar /trunk/uspace/srv/fs/fat/ Several fixes for the FAT file system:
- do not copy padding during file name canonization
- properly nul-terminate the FAT file name during canonization
- compare FAT file name and the component name case insensitively
- block_get() takes a block offset, not byte offset as parameter		  
3257 5806 d 22 h jermar /trunk/uspace/srv/fs/fat/ First attempt at delivering the FAT16 read-only support.
Needless to say it doesn't work yet, but now it's only
the lurking bugs that need to be fixed.		  
3253 5808 d 10 h jermar /trunk/uspace/srv/fs/fat/ Pass block size to block_get() in the last argument.  
3252 5808 d 10 h jermar /trunk/uspace/ Add a comment to libfs_blockread() and change type from size_t to off_t at
various places.		  
3251 5808 d 13 h jermar /trunk/uspace/ Move tmpfs_blockread() to libfs and rename it to libfs_blockread().
Add one argument to specify block size.		  
3250 5808 d 14 h jermar /trunk/uspace/srv/fs/tmpfs/ Let tmpfs_blockread() use async_req_2_1() instead of ipc_call_sync_2_1().  
3247 5809 d 13 h jermar /trunk/uspace/srv/fs/tmpfs/ Avoid magic numbers in tmpfs_dump.c.  
3201 5843 d 18 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3119 5869 d 17 h jermar /trunk/uspace/srv/fs/fat/ Initialize in-core FAT root directory node during mount.  
3111 5870 d 11 h jermar /trunk/uspace/srv/fs/fat/ Put a frequently used construct into a function.  
3110 5870 d 11 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 5870 d 16 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 5871 d 9 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 5873 d 12 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 5873 d 17 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk  
2958 5889 d 10 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2953 5890 d 11 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5890 d 12 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 5891 d 10 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5891 d 11 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 5895 d 15 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 5896 d 20 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5899 d 10 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5899 d 12 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 5902 d 11 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().
