2736 5998 d 0 h jermar /trunk/uspace/srv/fs/tmpfs/ Unlink a TMPFS node more thoroughly.  
2735 5998 d 4 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2733 5998 d 6 h jermar /trunk/uspace/ Add TMPFS support for destroying leaf links in the file system namespace.  
2732 5998 d 6 h jermar /trunk/uspace/srv/fs/tmpfs/ When freeing up a TMPFS node, it should also be removed from the dentries hash table.  
2731 5998 d 7 h jermar /trunk/uspace/srv/ Add the VFS_FREE operation. This operation frees up whatever resources used by
a file system node for which there is no name (i.e. an unlinked node).

Cleanup VFS operations enums and remove unneeded VFS operations.
 
2730 5999 d 9 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2728 6003 d 22 h jermar /trunk/uspace/srv/fs/tmpfs/ Descend vs. descent.  
2711 6019 d 1 h jermar /trunk/uspace/ Remove the debugging hack from tmpfs_init(), which created several files and
directories on the filesystem. TMPFS is now self-sufficient enough to be able
to create its content via the standard VFS interface.
 
2710 6019 d 1 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2707 6019 d 5 h jermar /trunk/uspace/ Support for mkdir().  
2706 6019 d 10 h jermar /trunk/uspace/srv/fs/tmpfs/ Move handling of the miss on excessive components out of the main loop in
tmpfs_lookup.
 
2705 6019 d 22 h jermar /trunk/uspace/ More elegant, flexible and complete version of tmpfs_lookup.  
2700 6027 d 7 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 6027 d 21 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 6033 d 7 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2690 6037 d 22 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 6038 d 0 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2686 6038 d 1 h jermar /trunk/uspace/srv/fs/tmpfs/ Previous commit was toxic. When emulating gaps, zero out the reallocated buffer, not the original one.  
2685 6038 d 1 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS must handle file gaps.  
2678 6046 d 3 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 6046 d 10 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 6046 d 23 h jermar /trunk/uspace/srv/fs/tmpfs/ Rename variable from 'size' to 'len'.  
2667 6051 d 19 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 6052 d 0 h jermar /trunk/uspace/srv/ VFS and TMPFS support for VFS_WRITE.  
2664 6053 d 22 h jermar /trunk/uspace/srv/fs/tmpfs/ Fix two bugs in TMPFS-side VFS_READ.  
2663 6053 d 23 h jermar /trunk/uspace/ Reimplement VFS_READ using IPC_M_DATA_READ.  
2658 6054 d 21 h jermar /trunk/uspace/srv/ VFS work.
Foundation for TMPFS-side VFS_READ and fixes in VFS-side VFS_READ.
 
2655 6058 d 3 h jermar /trunk/uspace/srv/fs/tmpfs/ TMPFS work.
VFS_LOOKUP implemented.
 
2645 6061 d 3 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 6061 d 3 h jermar /trunk/uspace/ Move incomplete fs interface from fat.h to libfs.  
2643 6061 d 4 h jermar /trunk/uspace/ VFS work.
Move FS registration code to libfs.
 
2639 6071 d 22 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.
 
2638 6073 d 0 h jermar /trunk/ Sync IPC comments with IPC code.  
2637 6073 d 0 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.
 
2635 6075 d 0 h cejka /trunk/ Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test.
 
2629 6081 d 23 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Add type describing FAT directory entry.
 
2628 6082 d 0 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Add type describing FAT boot sector.
 
2627 6082 d 1 h jermar /trunk/uspace/srv/fs/fat/ FAT work.
Start VFS_LOOKUP support in FAT.
 
2619 6086 d 23 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().
 
2615 6088 d 8 h jermar /trunk/ Modify synchronous IPC to make use of all six syscall arguments. The preferred
means of synchronous communication is now via the set of ipc_call_sync_m_n()
macros, where m is the number of payload arguments passed to the kernel and n is
the number of return values. These macros will automatically decide between the
fast and the universal slow version of ipc_call_sync.
