Changed the kernel's file_map.cpp to be usable from the fs_shell as well. * This should reduce our maintenance burden a tiny bit :-) * It also fixes a bug in the fs_shell, see hrev43395.

* bfs_fsync() was the only place which could cause the fs_vnode_ops::write_pages() to be called with fsReenter = true. Since this is no longer the case, the argument has become superfluous. For read_pages() it always was. Removed the argument from the functions and all functions that propagated it. * Some whitespace at the end of lines was removed. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26579 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Made the private kernel locking primitives available to file systems as well. * Applied Korli's mutex_unlock() fix to block_cache.cpp. * Removed block_cache_priv.h, as it's no longer needed (moved its definitions into block_cache.cpp, as in the kernel file). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26296 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Extracted file_map API out of the file cache - it's now an optional service that can be used by file systems. * Changed the way the file cache works: instead of reading/writing to the underlying device directly, it can now be used for any data source, ie. also network file systems. * As a result, the former pages_io() moved to the VFS layer, and can now be called by a file system via {read|write}_file_io_vec_pages() (naming suggestions are always welcomed :-)). It now gets an FD, and uses that to communicate with the device (via its fs_{read|write}_pages() hooks). * The file_cache_{read|write}() functions must now be called without holding an I/O relevant file system lock. That allows the file cache to prepare the pages without colliding with the page writer, IOW the "mayBlock" flag can go into the attic again (yay!). * This also results in a much better performance when the system does I/O and is low on memory, as the page writer can now finally write back some pages, and that even without maxing out the CPU :) * The API changes put slightly more burden on the fs_{read|write}_pages() hooks, but in combination with the file_map it's still pretty straight forward. It just will have to dispatch the call to the underlying device directly, usually it will just call its fs_{read|write}_pages() hooks via the above mentioned calls. * Ported BFS and FAT to the new API, the latter has not been tested, though. * Also ported the API changes to the fs_shell. I also completely removed its file cache level page handling - the downside is that device access is no longer cached (ie. depends on the host OS now), the upside is that the code is greatly simplified. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22886 a95241bf-73f2-0310-859d-f6bbb57e9c96

Beginnings of a new, better portable FS shell with Haiku FS interface. Doesn't do anything ATM, but already provides the required system interface (VFS, caches, POSIX functions). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20859 a95241bf-73f2-0310-859d-f6bbb57e9c96
