fatfs/
2005-07-12 Marcus Brinkmann <marcus@gnu.org>
* pager.c (diskfs_get_filemap): Initialize upi->max_prot to PROT.
|
|
* fat.h: Include <byteswap.h>.
|
|
* fat.h (read_dword) [BYTE_ORDER == BIG_ENDIAN]: Use bswap_32 to
swap bytes.
(write_dword) [BYTE_ORDER == BIG_ENDIAN]: Likewise.
(read_word) [BYTE_ORDER == BIG_ENDIAN]: Use bswap_16 to swap bytes.
(write_word) [BYTE_ORDER == BIG_ENDIAN]: Likewise.
|
|
* fatfs.h (struct disknode): New member DIRNODE.
* inode.c (read_node): Added assertion to be sure the directory
can always be found. Add directory dependancy to node by
initializing DIRNODE and holding a reference.
(diskfs_node_norefs): Release reference to DIRNODE.
(write_node): Don't use diskfs_cached_lookup to lookup the
directory, use DIRNODE instead and lock DP. Don't use diskfs_nput,
use mutex_unlock instead.
(diskfs_alloc_node): Add directory dependancy to node by
initializing DIRNODE and holding a reference.
|
|
* fat.c (fat_read_sblock): Catch error from store_read.
|
|
* inode.c (read_node): Fix typo.
|
|
* node-create.c: New file.
* Makefile (SRCS): Added node-created.c.
* dir.c: Include <hurd/fsys.h>.
(diskfs_direnter_hard): Initialize a new block with zeros. Enter
direntry and setup the virtual inode. Also handle directories
correctly.
(diskfs_rewrite_hard): Function rewritten.
(diskfs_dirempty): Change logic to test if a file was deleted.
* fat.c (fat_extend_chain): Unlock spin_lock when returning from
function. Set dn->last to 0 when deallocating the complete
file. Update dn->last when not deallocating the complete file. Set
dn->first to zero when the complete file was deallocated. Also
update dn->length_of_chain to the new amount of clusters in the
chain.
* main.c (diskfs_hard_readonly): Remove global variable.
|
|
|
|
* fatfs.h (LOG2_BLOCKS_PER_CLUSTER): Fix typo.
|
|
* pager.c (find_cluster): Round to cluster size rather than adding
cluster size.
|
|
* fat.c (fat_read_sblock): Don't test if the root dir size is a
multiple of sectors_per_cluster. Reported by Barry deFreese
(bddebian@cox.net).
* fatfs.h (LOG2_BLOCKS_PER_CLUSTER): New macro.
(FAT_FIRST_CLUSTER_BLOCK): Likewise.
(fat_first_cluster_byte): Macro removed.
* inode.c (read_node): Correctly setup diskfs_root_node for FAT32
filesystems.
* pager.c (fat_getcluster): Check for reading beyond allocsize
correctly for file systems with a clustersize > vm_page_size.
(file_pager_read_small_page): Don't use byte offsets when
calculating the block.
(file_pager_read_huge_page): Likewise.
(pending_clusters_write): Likewise.
(file_pager_write_small_page): Likewise.
(STAT_INC): Cast to void to suppress warning.
|
|
* dir.c (diskfs_get_directs): Consider ENTRY when adding
"." and ".." for the rootnode.
* inode.c (read_node): Use ifind instead of diskfs_cached_lookup
and do not use diskfs_nput anymore.
* main.c (diskfs_S_fsys_getfile): New function.
