3574 5741 d 0 h jermar /trunk/uspace/srv/fs/fat/ Move common code to dedicated functions so that it can be easily reused.  
3573 5741 d 2 h jermar /trunk/uspace/srv/fs/fat/ VFS_WRITE has two return arguments on success.  
3572 5741 d 4 h jermar /trunk/uspace/srv/fs/fat/ Finish implementation of fat_truncate() and fix several warnings.  
3571 5741 d 7 h jermar /trunk/uspace/ Simplify the fat_cluster_walk() interface.
Introduce the bn_t type for holding block offsets.		  
3568 5742 d 10 h svoboda /trunk/uspace/ Always include Makefile.config instead of passing ARCH and COMPILER to child make on the command line. Allows running make on individual apps and allows more configuration options.  
3551 5744 d 23 h jermar /trunk/uspace/srv/fs/fat/ Need to initialize the lcl variable via a call to fat_cluster_walk().  
3550 5744 d 23 h jermar /trunk/uspace/srv/fs/fat/ Extend _fat_blcks_get() to fat_cluster_walk(). Use fat_cluster_walk() to
implement fat_clusters_get() and _fat_block_get().		  
3548 5745 d 22 h jermar /trunk/uspace/srv/fs/fat/ More fat_truncate() bits.  
3547 5745 d 23 h jermar /trunk/uspace/srv/fs/fat/ Enable fat_write().  
3546 5745 d 23 h jermar /trunk/uspace/srv/fs/fat/ Start implementing fat_truncate().  
3542 5748 d 3 h jermar /trunk/uspace/ Do not use/pass the superfluous block size argument to block_get().  
3539 5748 d 8 h jermar /trunk/uspace/ Add block_cache_init().  
3537 5748 d 11 h jermar /trunk/uspace/ Separate the block_init() phase from reading of the boot block.  
3533 5750 d 5 h jermar /trunk/uspace/srv/fs/fat/ move comment  
3532 5750 d 5 h jermar /trunk/uspace/srv/fs/fat/ fat_read() needs to stop reading beyond the EOF.  
3530 5753 d 6 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 5753 d 23 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 5754 d 4 h jermar /trunk/uspace/ Move libfs_blockread(), block_get() and block_put() to libblock.  
3519 5754 d 6 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_node_sync().  
3518 5754 d 7 h jermar /trunk/uspace/srv/fs/fat/ Add comments to functions in fat_fat.c.  
3517 5754 d 8 h jermar /trunk/uspace/srv/fs/fat/ Add FAT allocation futex.  
3516 5754 d 9 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 5755 d 2 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_append_clusters().  
3512 5755 d 3 h jermar /trunk/uspace/srv/fs/fat/ Make sure that data are converted from / to the native endianity when writing them
out to / reading them in from the file system.		  
3510 5755 d 4 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_mark_cluster().  
3507 5755 d 6 h jermar /trunk/uspace/srv/fs/fat/ Implement fat_alloc_shadow_clusters().  
3506 5755 d 7 h jermar /trunk/uspace/srv/fs/fat/ Move functionality related to manipulatings file allocation tables to fat_fat.c.  
3505 5755 d 8 h jermar /trunk/uspace/srv/fs/fat/ Move functionality related to FAT dentries to fat_dentry.c.  
3504 5755 d 9 h jermar /trunk/uspace/srv/fs/fat/ Prepare to break fat_ops.c into multiple files.  
3503 5755 d 10 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_alloc_clusters().  
3501 5756 d 2 h jermar /trunk/uspace/srv/fs/fat/ Implementation of fat_fill_gap().  
3500 5756 d 4 h jermar /trunk/uspace/srv/fs/fat/ More complete prototype of fat_write().  
3499 5756 d 6 h jermar /trunk/uspace/srv/fs/fat/ Mark progress in fat_write().  
3497 5756 d 11 h jermar /trunk/uspace/srv/fs/fat/ Dummy fat_write().  
3352 5820 d 2 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 5824 d 0 h jermar /trunk/uspace/srv/fs/fat/ Support for readdir() on FAT.  
3325 5827 d 1 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 5828 d 2 h jermar /trunk/uspace/srv/fs/fat/ fat_read() should expect IPC_M_DATA_READ instead of IPC_M_DATA_WRITE.  
3312 5828 d 2 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 5830 d 1 h jermar /trunk/uspace/srv/fs/fat/ More complete fat_read().
