4370	6169 d 20 h	jermar	/trunk/uspace/	Streamline TMPFS and fix its design so that it properly supports hardlinks. libfs operation unlink() is now passed also the name of the component being unlinked.
4357	6173 d 20 h	jermar	/trunk/uspace/	Introduce the concept of FS nodes. A FS node is a typed abstraction of file-system-specific node type. It replaces the void * in libfs interfaces and is suitable for holding various information such as mount point data.
4306	6190 d 21 h	jermar	/trunk/uspace/srv/fs/tmpfs/	Support multiple TMPFS instances.
4305	6191 d 2 h	jermar	/trunk/uspace/	Support mount options. Let tmpfs decide whether to start empty or restored a TMPFS dump based on the mount option.
4268	6199 d 10 h	svoboda	/trunk/uspace/	str_cpy() and str_ncpy() in userspace. Nuke strcpy() and strncpy().
4264	6199 d 20 h	svoboda	/trunk/uspace/	Nuke strcpy() and strcmp().
3625	6337 d 5 h	jermar	/trunk/uspace/	libfs operation link() should return standard error code instead of mere true/false.
3575	6350 d 20 h	jermar	/trunk/uspace/	libfs create operation should take the device handle as argument.
3352	6429 d 22 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().
3109	6507 d 2 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	6507 d 19 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	6509 d 22 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	6510 d 2 h	decky	/trunk/uspace/srv/fs/tmpfs/	initialize tmpfs from RAM disk
2958	6525 d 20 h	jermar	/trunk/uspace/srv/	Make VFS_MOUNT call even when mounting the root file system.
2863	6554 d 6 h	jermar	/trunk/uspace/	Revert libfs node_get() API to a model without the parent node pointer argument.
2858	6559 d 14 h	jermar	/trunk/uspace/	libfs destroy operation should rather return an error code instead of a truth value.
2857	6559 d 15 h	jermar	/trunk/uspace/	Add stubs for unimplemented FAT libfs operations.
2852	6560 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.
2844	6561 d 19 h	jermar	/trunk/uspace/	Add fat_root_get() and fat_plb_get_char().
2831	6564 d 13 h	jermar	/trunk/uspace/	Commit progress on the FAT file system server implementation.
