2707 5971 d 13 h jermar /trunk/uspace/ Support for mkdir().  
2706 5971 d 18 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.		  
2705 5972 d 6 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 5979 d 15 h jermar /trunk/uspace/ Introduce the notion of lflag (i.e. lookup flags) to support the ability to
limit the scope of VFS node types that can be opened by open() and opendir(). In
the future, lflag will also specify actions for VFS_LOOKUP handlers that will be
carried out in situations such as the VFS node is not found (e.g. implementation
of mkdir() and open() with O_CREAT in oflag).		  
2699 5980 d 5 h jermar /trunk/uspace/ Finish implementation of readdir(). Functions from this family are implemented
via using file descriptors for directories. For example, readdir() is
implemented as read() from an open directory. Of course, FS implementations
must understand that they are asked to read a directory and behave accordingly.		  
2693 5985 d 15 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2687 5990 d 8 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 5990 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 5990 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.  
2678 5998 d 11 h jermar /trunk/uspace/ The IPC_M_SHARE_* and IPC_M_DATA_* calls pass through 3 stages. Rename the send,
receive and deliver wrappers to names ending with 'start', 'receive' and
'finalize', respectively. This should make it clearer for dummies.		  
2676 5998 d 18 h jermar /trunk/ Simplify the IPC_M_DATA_WRITE protocol. Do not pass the source address space
virtual address to the recipient. This feature was not used anyway. Now
IPC_M_DATA_WRITE and IPC_M_DATA_READ are feature-aligned.		  
2673 5999 d 7 h jermar /trunk/uspace/srv/fs/tmpfs/ Rename variable from 'size' to 'len'.  
2667 6004 d 4 h jermar /trunk/uspace/srv/fs/tmpfs/ The previous commit was not entirely sane.
Handle VFS_WRITE correctly when the file doesn't grow.
Handle it correctly also when the file grows.		  
2666 6004 d 8 h jermar /trunk/uspace/srv/ VFS and TMPFS support for VFS_WRITE.  
2664 6006 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ Fix two bugs in TMPFS-side VFS_READ.  
2663 6006 d 7 h jermar /trunk/uspace/ Reimplement VFS_READ using IPC_M_DATA_READ.  
2658 6007 d 5 h jermar /trunk/uspace/srv/ VFS work.
Foundation for TMPFS-side VFS_READ and fixes in VFS-side VFS_READ.		  
2655 6010 d 11 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS work.
VFS_LOOKUP implemented.		  
2645 6013 d 11 h jermar /trunk/uspace/ Start TMPFS.
Not loaded during boot as there is a reproducible kernel panic which occurs when
both tmpfs and fat are loaded.
