2700 5985 d 18 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 5986 d 7 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 5991 d 18 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2690 5996 d 9 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.		  
2687 5996 d 11 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 5996 d 12 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 5996 d 12 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.  
2678 6004 d 14 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 6004 d 21 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 6005 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Rename variable from 'size' to 'len'.  
2667 6010 d 6 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 6010 d 11 h jermar /trunk/uspace/srv/ VFS and TMPFS support for VFS_WRITE.  
2664 6012 d 9 h jermar /trunk/uspace/srv/fs/tmpfs/ Fix two bugs in TMPFS-side VFS_READ.  
2663 6012 d 9 h jermar /trunk/uspace/ Reimplement VFS_READ using IPC_M_DATA_READ.  
2658 6013 d 8 h jermar /trunk/uspace/srv/ VFS work.
Foundation for TMPFS-side VFS_READ and fixes in VFS-side VFS_READ.		  
2655 6016 d 14 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS work.
VFS_LOOKUP implemented.		  
2645 6019 d 14 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.		  
2644 6019 d 14 h jermar /trunk/uspace/ Move incomplete fs interface from fat.h to libfs.  
2643 6019 d 15 h jermar /trunk/uspace/ VFS work.
Move FS registration code to libfs.		  
2639 6030 d 8 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.
