3003 5874 d 2 h jermar /trunk/uspace/lib/libfs/ More of the preivous commit.  
3002 5874 d 2 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 5881 d 0 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5881 d 1 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 5882 d 0 h jermar /trunk/uspace/srv/fs/fat/ Add synchronization to fat_match().  
2951 5882 d 1 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 5883 d 0 h jermar /trunk/uspace/srv/fs/fat/ Introduce a futex protecting the up_hash and ui_hash.  
2944 5883 d 0 h jermar /trunk/uspace/srv/fs/fat/ Introduce futex for protecting the list of unused structures in FAT server.  
2934 5884 d 3 h jermar /trunk/ Do not attempt to malloc() zero bytes of memory during VFS_READ at end of file.  
2926 5884 d 12 h decky /trunk/kernel/generic/include/proc/ cs change  
2916 5887 d 2 h jermar /trunk/kernel/generic/src/ More formatting changes.  
2914 5887 d 3 h jermar /trunk/kernel/generic/src/synch/ Formatting improvements.  
2910 5887 d 5 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().		  
2909 5887 d 6 h jermar /trunk/kernel/generic/src/synch/ timeouted vs. timed out  
2907 5887 d 6 h jermar /trunk/kernel/generic/src/proc/ Improve comment for thread_create().  
2893 5888 d 10 h jermar /trunk/uspace/srv/fs/fat/ More bits of fat_node_get().
Still needs to do some locking.		  
2891 5891 d 0 h jermar /trunk/uspace/srv/fs/fat/ New first bits of fat_node_get().  
2890 5891 d 2 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 5894 d 1 h jermar /trunk/uspace/srv/fs/fat/ Add hash table for used fat_idx_t structures and implement fat_idx_map().  
2884 5895 d 1 h jermar /trunk/uspace/srv/fs/fat/ merge vs. coalesce  
2881 5895 d 5 h jermar /trunk/uspace/srv/fs/fat/ Code for de/allocation of VFS indices for FAT.  
2879 5895 d 6 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 5895 d 9 h jermar /trunk/uspace/srv/fs/fat/ Add a dedicated source file for handling FAT indices.  
2864 5908 d 23 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 5909 d 10 h jermar /trunk/uspace/ Revert libfs node_get() API to a model without the parent node pointer
argument.		  
2861 5913 d 2 h cejka /trunk/ Used common macro for context saving on ppc64.  
2860 5914 d 1 h cejka /trunk/ Context handling unified for sparc64.  
2859 5914 d 15 h jermar /trunk/uspace/srv/fs/fat/ Add fat_block_get().  
2858 5914 d 18 h jermar /trunk/uspace/ libfs destroy operation should rather return an error code instead of a truth
value.		  
2857 5914 d 18 h jermar /trunk/uspace/ Add stubs for unimplemented FAT libfs operations.  
2856 5914 d 19 h jermar /trunk/uspace/srv/fs/fat/ Add a locking scheme for FAT in-core cache and nodes.  
2855 5914 d 20 h jermar /trunk/uspace/srv/fs/fat/ fat_node_put(). No locking so far.  
2852 5915 d 16 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.		  
2847 5916 d 19 h jermar /trunk/uspace/lib/libfs/ Reset the component length variable only prior collecting a new component.  
2846 5916 d 19 h jermar /trunk/uspace/lib/libfs/ Improve libfs_lookup() so that has_children() is not called for each character
in the pathname component.		  
2845 5916 d 22 h jermar /trunk/uspace/srv/fs/fat/ Add fat_has_children(). Alse assume that fat_block_get() can never return NULL.  
2844 5916 d 23 h jermar /trunk/uspace/ Add fat_root_get() and fat_plb_get_char().  
2843 5917 d 0 h jermar /trunk/uspace/srv/fs/fat/ Somewhat complete implementation of fat_node_get().  
2831 5919 d 16 h jermar /trunk/uspace/ Commit progress on the FAT file system server implementation.  
2830 5920 d 5 h jermar /trunk/ Add (c) and the modified BSD license to the config system.
