4586 5608 d 17 h jermar /trunk/uspace/ Add libfs_stat() and let FAT and TMPFS use it.  
4585 5608 d 17 h jermar /trunk/uspace/ Introduce VFS_IN_FSTAT and VFS_OUT_STAT.
Provide libc fstat() and devfs_stat().
This functionality replaces VFS_IN_NODE
and VFS_IN/OUT_DEVICE. FAT and TMPFS
still do not implement this and VFS_IN_STAT
and stat() need implementation as well.		  
4509 5628 d 22 h decky /trunk/uspace/ rename libadt -> adt  
4465 5633 d 17 h decky /trunk/uspace/srv/fs/ implement VFS_OPEN_NODE and VFS_DEVICE (no device handle is returned)
implement no-op VFS_SYNC and VFS_CLOSE		  
4429 5645 d 17 h jermar /trunk/uspace/ Add fs_handle argument to libfs_mount() needed to recognize homogenous mounts.  
4424 5646 d 17 h jermar /trunk/uspace/srv/fs/tmpfs/ Call libfs_mount() from tmpfs_mount().  
4409 5648 d 14 h jermar /trunk/uspace/ Rudimentary support for non-root mounts.  
4370 5658 d 14 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 5662 d 14 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 5679 d 16 h jermar /trunk/uspace/srv/fs/tmpfs/ Support multiple TMPFS instances.  
4305 5679 d 20 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 5688 d 4 h svoboda /trunk/uspace/ str_cpy() and str_ncpy() in userspace. Nuke strcpy() and strncpy().  
4264 5688 d 15 h svoboda /trunk/uspace/ Nuke strcpy() and strcmp().  
3625 5825 d 23 h jermar /trunk/uspace/ libfs operation link() should return standard error code instead of mere
true/false.		  
3575 5839 d 14 h jermar /trunk/uspace/ libfs create operation should take the device handle as argument.  
3352 5918 d 16 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 5995 d 21 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 5996 d 13 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 5998 d 16 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 5998 d 21 h decky /trunk/uspace/srv/fs/tmpfs/ initialize tmpfs from RAM disk
