Rev	Age	Author	Path	Log message
4424	5509 d 0 h	jermar	/trunk/uspace/srv/fs/tmpfs/	Call libfs_mount() from tmpfs_mount().
4409	5510 d 21 h	jermar	/trunk/uspace/	Rudimentary support for non-root mounts.
4370	5520 d 21 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	5524 d 21 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	5541 d 23 h	jermar	/trunk/uspace/srv/fs/tmpfs/	Support multiple TMPFS instances.
4305	5542 d 3 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	5550 d 11 h	svoboda	/trunk/uspace/	str_cpy() and str_ncpy() in userspace. Nuke strcpy() and strncpy().
4264	5550 d 22 h	svoboda	/trunk/uspace/	Nuke strcpy() and strcmp().
3625	5688 d 6 h	jermar	/trunk/uspace/	libfs operation link() should return standard error code instead of mere true/false.
3575	5701 d 21 h	jermar	/trunk/uspace/	libfs create operation should take the device handle as argument.
3352	5780 d 23 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	5858 d 4 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	5858 d 20 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	5860 d 23 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	5861 d 4 h	decky	/trunk/uspace/srv/fs/tmpfs/	initialize tmpfs from RAM disk
2958	5876 d 21 h	jermar	/trunk/uspace/srv/	Make VFS_MOUNT call even when mounting the root file system.
2863	5905 d 7 h	jermar	/trunk/uspace/	Revert libfs node_get() API to a model without the parent node pointer argument.
2858	5910 d 16 h	jermar	/trunk/uspace/	libfs destroy operation should rather return an error code instead of a truth value.
2857	5910 d 16 h	jermar	/trunk/uspace/	Add stubs for unimplemented FAT libfs operations.
2852	5911 d 14 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.
