3250 5768 d 5 h jermar /trunk/uspace/srv/fs/tmpfs/ Let tmpfs_blockread() use async_req_2_1() instead of ipc_call_sync_2_1().  
3247 5769 d 5 h jermar /trunk/uspace/srv/fs/tmpfs/ Avoid magic numbers in tmpfs_dump.c.  
3201 5803 d 10 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3119 5829 d 8 h jermar /trunk/uspace/srv/fs/fat/ Initialize in-core FAT root directory node during mount.  
3111 5830 d 3 h jermar /trunk/uspace/srv/fs/fat/ Put a frequently used construct into a function.  
3110 5830 d 3 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 5830 d 8 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 5831 d 1 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 5833 d 4 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 5833 d 8 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk  
2958 5849 d 1 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2953 5850 d 2 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5850 d 3 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 5851 d 2 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5851 d 2 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2910 5855 d 7 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 5856 d 12 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5859 d 2 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5859 d 4 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 5862 d 3 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5863 d 2 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5863 d 7 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2876 5863 d 11 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5877 d 1 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 5877 d 12 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2859 5882 d 17 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5882 d 20 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5882 d 20 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5882 d 21 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5882 d 21 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5883 d 18 h jermar /trunk/uspace/ Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.
Add node_put() to libfs operations and instrument libfs_lookup() to use it at
appropriate places.		  
2845 5885 d 0 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5885 d 1 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5885 d 2 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5887 d 18 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2828 5888 d 22 h jermar /trunk/uspace/srv/fs/fat/ BPS read from FAT bootsector is little-endian. It must converted to host
endianity before being used.		  
2822 5889 d 22 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2798 5894 d 3 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.  
2796 5895 d 3 h jermar /trunk/uspace/srv/fs/fat/ Convert FAT on-disk metadata from little-endian to native representation.  
2793 5895 d 4 h jermar /trunk/uspace/srv/fs/fat/ First untested bits of FAT lookup support.
