2891	5999 d 20 h	jermar	/trunk/uspace/srv/fs/fat/	New first bits of fat_node_get().
2890	5999 d 22 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	6002 d 21 h	jermar	/trunk/uspace/srv/fs/fat/	Add hash table for used fat_idx_t structures and implement fat_idx_map().
2884	6003 d 20 h	jermar	/trunk/uspace/srv/fs/fat/	merge vs. coalesce
2881	6004 d 1 h	jermar	/trunk/uspace/srv/fs/fat/	Code for de/allocation of VFS indices for FAT.
2876	6004 d 5 h	jermar	/trunk/uspace/srv/fs/fat/	Add a dedicated source file for handling FAT indices.
2864	6017 d 19 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	6018 d 6 h	jermar	/trunk/uspace/	Revert libfs node_get() API to a model without the parent node pointer argument.
2859	6023 d 11 h	jermar	/trunk/uspace/srv/fs/fat/	Add fat_block_get().
2858	6023 d 14 h	jermar	/trunk/uspace/	libfs destroy operation should rather return an error code instead of a truth value.
2857	6023 d 14 h	jermar	/trunk/uspace/	Add stubs for unimplemented FAT libfs operations.
2856	6023 d 15 h	jermar	/trunk/uspace/srv/fs/fat/	Add a locking scheme for FAT in-core cache and nodes.
2855	6023 d 15 h	jermar	/trunk/uspace/srv/fs/fat/	fat_node_put(). No locking so far.
2852	6024 d 12 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	6025 d 18 h	jermar	/trunk/uspace/srv/fs/fat/	Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.
2844	6025 d 19 h	jermar	/trunk/uspace/	Add fat_root_get() and fat_plb_get_char().
2843	6025 d 20 h	jermar	/trunk/uspace/srv/fs/fat/	Somewhat complete implementation of fat_node_get().
2831	6028 d 12 h	jermar	/trunk/uspace/	Commit progress on the FAT file system server implementation.
2828	6029 d 16 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	6030 d 16 h	jermar	/trunk/uspace/srv/fs/fat/	Introduce and also use the foundation of block cache API in FAT's match operation.
2798	6034 d 20 h	jermar	/trunk/uspace/	Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.
2796	6035 d 21 h	jermar	/trunk/uspace/srv/fs/fat/	Convert FAT on-disk metadata from little-endian to native representation.
2793	6035 d 21 h	jermar	/trunk/uspace/srv/fs/fat/	First untested bits of FAT lookup support.
2789	6041 d 9 h	jermar	/trunk/uspace/srv/fs/fat/	Fix FAT boot sector definition and introduce the FAT in-core node type.
2731	6081 d 4 h	jermar	/trunk/uspace/srv/	Add the VFS_FREE operation. This operation frees up whatever resources used by a file system node for which there is no name (i.e. an unlinked node). Cleanup VFS operations enums and remove unneeded VFS operations.
2690	6120 d 19 h	jermar	/trunk/uspace/srv/	Make a distinction between VFS operations that are common to VFS and FS implementations, operations that are VFS only and operations that are FS implementations only.
2644	6144 d 0 h	jermar	/trunk/uspace/	Move incomplete fs interface from fat.h to libfs.
2643	6144 d 1 h	jermar	/trunk/uspace/	VFS work. Move FS registration code to libfs.
2639	6154 d 19 h	jermar	/trunk/uspace/srv/fs/fat/	FAT work. Foundation for FAT dentry comparison function. Beware of looking at the diff or risk loosing sanity.
2638	6155 d 21 h	jermar	/trunk/	Sync IPC comments with IPC code.
2637	6155 d 21 h	cejka	/trunk/	Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters. Phone identifier is passed in ARG5.
2635	6157 d 21 h	cejka	/trunk/	Function ipc_connect_me_to sends 3 user defined arguments now. One argument added also to ipc_forward_fast. Fixed devmap and improved its test.
2629	6164 d 20 h	jermar	/trunk/uspace/srv/fs/fat/	FAT work. Add type describing FAT directory entry.
2628	6164 d 20 h	jermar	/trunk/uspace/srv/fs/fat/	FAT work. Add type describing FAT boot sector.
2627	6164 d 22 h	jermar	/trunk/uspace/srv/fs/fat/	FAT work. Start VFS_LOOKUP support in FAT.
2619	6169 d 20 h	jermar	/trunk/	Modify ipc_answer_*() to make use of all six syscall arguments. The recommended means of answering calls is via the ipc_answer_m() macros (where m denotes the number of return arguments) that automatically decide between the fast register version or the slow universal version of ipc_answer().
2615	6171 d 5 h	jermar	/trunk/	Modify synchronous IPC to make use of all six syscall arguments. The preferred means of synchronous communication is now via the set of ipc_call_sync_m_n() macros, where m is the number of payload arguments passed to the kernel and n is the number of return values. These macros will automatically decide between the fast and the universal slow version of ipc_call_sync.
2588	6187 d 2 h	jermar	/trunk/uspace/	Add ipc_answer_fast_[01] macros so that ipc_answer_fast() users don't have to write zero arguments all the time.
2568	6218 d 10 h	jermar	/trunk/uspace/	Rename fibril_schedule_next_adv() to fibril_switch(). Rename fibril_schedule_next() to fibril_yield(). Some fibril structures could be uninitialized, set them to zero in fibril_setup(). For some fibrils, the stack member can be NULL (e.g. every thread's first/main fibril); don't do free on these stacks when cleaning up after a dead fibril.
2546	6223 d 7 h	jermar	/trunk/uspace/srv/	VFS work. Upon FS registration via VFS_REGISTER, the client is assigned a unique file system handle. When generating the VFS_LOOKUP request in VFS, we also need to pass the device handle. Add function to transform file system handle to phone. Implement basic multi-call VFS request serialization on VFS side.
