3002 5898 d 19 h jermar /trunk/uspace/lib/libfs/ Optimize conditions in libfs_lookup(). Perform primitive comparisons in the
left-hand subexpression and potentially expensive calls to libfs operations in
the right-hand subexpression.		  
2958 5905 d 16 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5905 d 18 h jermar /trunk/uspace/srv/vfs/ Cram VFS_MOUNT into one message. This creates a hidden demand for the sixth IPC
argument as there might be a desire to pass some options/flags in the future.		  
2953 5906 d 17 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5906 d 18 h jermar /trunk/uspace/srv/fs/fat/ Add locks to FAT index structures, FAT in-core node structures. Add futex to
protect the list of free cached FAT in-core nodes. Make fat_node_get() and
fat_node_put() and some other functions aware of these new locks.		  
2945 5907 d 17 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5907 d 17 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2934 5908 d 20 h jermar /trunk/ Do not attempt to malloc() zero bytes of memory during VFS_READ at end of file.  
2910 5911 d 22 h jermar /trunk/uspace/srv/fs/fat/ Implement fat_node_put() and remove the node from the free node list when
bumping its refernce count from zero in fat_node_get().		  
2893 5913 d 3 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5915 d 17 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5915 d 19 h jermar /trunk/uspace/srv/fs/fat/ Need a way to locate the FAT index structure by VFS index. Also fix code that
locates the FAT index structure by position in the file system namespace.		  
2889 5918 d 18 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5919 d 18 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5919 d 22 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2879 5919 d 23 h jermar /trunk/uspace/lib/libc/include/libadt/ Add functions for inserting items before or after other items in a boubly-linked
circular lists.		  
2876 5920 d 2 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5933 d 16 h jermar /trunk/uspace/srv/fs/fat/ Introduce the foundation for unique and stable FAT VFS node indices.

The first two reserved FAT entries are physically present in each FAT, so fix
the code to be aware of this.		  
2863 5934 d 3 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2861 5937 d 18 h cejka /trunk/ Used common macro for context saving on ppc64.  
2860 5938 d 18 h cejka /trunk/ Context handling unified for sparc64.  
2859 5939 d 8 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5939 d 11 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5939 d 11 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5939 d 12 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5939 d 13 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5940 d 9 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.
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.		  
2847 5941 d 11 h jermar /trunk/uspace/lib/libfs/ Reset the component length variable only prior collecting a new component.  
2846 5941 d 12 h jermar /trunk/uspace/lib/libfs/ Improve libfs_lookup() so that has_children() is not called for each character
in the pathname component.		  
2845 5941 d 15 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5941 d 16 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5941 d 17 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5944 d 9 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2830 5944 d 22 h jermar /trunk/ Add (c) and the modified BSD license to the config system.  
2828 5945 d 13 h jermar /trunk/uspace/srv/fs/fat/ BPS read from FAT bootsector is little-endian. It must converted to host
endianity before being used.		  
2822 5946 d 13 h jermar /trunk/uspace/srv/fs/fat/ Introduce and also use the foundation of block cache API in FAT's match
operation.		  
2821 5946 d 13 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2820 5946 d 16 h decky /trunk/uspace/lib/libc/generic/ fix copy-paste typo  
2814 5947 d 1 h jermar /trunk/uspace/lib/libc/include/ipc/ Fix missing arguments to ipc_call_sync_slow() in ipc_call_sync_4_x macros.

2798 5950 d 18 h jermar /trunk/uspace/ Replace all endian.h in uspace with a copy of the kernel's respective byteorder.h.
