3539 5702 d 0 h jermar /trunk/uspace/ Add block_cache_init().  
3537 5702 d 4 h jermar /trunk/uspace/ Separate the block_init() phase from reading of the boot block.  
3533 5703 d 21 h jermar /trunk/uspace/srv/fs/fat/ move comment  
3532 5703 d 22 h jermar /trunk/uspace/srv/fs/fat/ fat_read() needs to stop reading beyond the EOF.  
3530 5706 d 22 h jermar /trunk/uspace/ Setup communication parameters with the block device in block_init(). The file
system now doesn't know anything about the communication with the block device.
Rename blockread() to block_read(). The boot block is now read only once. The file
system can get access it using the block_bb_get() function.		  
3526 5707 d 15 h jermar /trunk/uspace/srv/fs/fat/ Directory size is always a multiple of BPS. Fix computation of number of
directory entries in the last block of the directory.		  
3521 5707 d 21 h jermar /trunk/uspace/ Move libfs_blockread(), block_get() and block_put() to libblock.  
3519 5707 d 23 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_node_sync().  
3516 5708 d 1 h jermar /trunk/uspace/srv/fs/fat/ Pass the buffer holding the boot sector to the internal functions so that it
doesn't have to be block_get()'ed in each function. The idea is that the boot
block should be read by the top-level functions in fat_ops.c and passed down the
call chain.		  
3513 5708 d 18 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_append_clusters().  
3506 5709 d 0 h jermar /trunk/uspace/srv/fs/fat/ Move functionality related to manipulatings file allocation tables to fat_fat.c.  
3505 5709 d 1 h jermar /trunk/uspace/srv/fs/fat/ Move functionality related to FAT dentries to fat_dentry.c.  
3503 5709 d 2 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_alloc_clusters().  
3501 5709 d 18 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_fill_gap().  
3500 5709 d 20 h jermar /trunk/uspace/srv/fs/fat/ More complete prototype of fat_write().  
3499 5709 d 23 h jermar /trunk/uspace/srv/fs/fat/ Mark progress in fat_write().  
3497 5710 d 3 h jermar /trunk/uspace/srv/fs/fat/ Dummy fat_write().  
3352 5773 d 18 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 5777 d 17 h jermar /trunk/uspace/srv/fs/fat/ Support for readdir() on FAT.  
3325 5780 d 18 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 5781 d 18 h jermar /trunk/uspace/srv/fs/fat/ fat_read() should expect IPC_M_DATA_READ instead of IPC_M_DATA_WRITE.  
3312 5781 d 19 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 5783 d 17 h jermar /trunk/uspace/srv/fs/fat/ More complete fat_read().  
3307 5783 d 19 h jermar /trunk/uspace/srv/fs/fat/ Dummy implementation of fat_read().  
3282 5785 d 15 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 5786 d 5 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 5787 d 4 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 5788 d 16 h jermar /trunk/uspace/srv/fs/fat/ Pass block size to block_get() in the last argument.  
3119 5849 d 23 h jermar /trunk/uspace/srv/fs/fat/ Initialize in-core FAT root directory node during mount.  
3110 5850 d 18 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.		  
2953 5870 d 17 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5870 d 18 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.		  
2910 5875 d 22 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 5877 d 3 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5879 d 16 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5879 d 19 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.		  
2881 5883 d 22 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5884 d 1 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5897 d 15 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 5898 d 3 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.
