rc4bbca8 r616e73c 65 65 * The connection fibril accepts VFS requests from VFS. If there is only one 66 66 * instance of the fibril, VFS will need to serialize all VFS requests it sends 67 * to FAT. To overcome this bottleneck, VFS can send FAT the IPC_M_CONNECT_ME_TO67 * to FAT. To overcome this bottleneck, VFS can send exFAT the IPC_M_CONNECT_ME_TO 68 68 * call. In that case, a new connection fibril will be created, which in turn 69 69 * will accept the call. Thus, a new phone will be opened for VFS. … … 71 71 * There are few issues with this arrangement. First, VFS can run out of 72 72 * available phones. In that case, VFS can close some other phones or use one 73 * phone for more serialized requests. Similarily, FAT can refuse to duplicate73 * phone for more serialized requests. Similarily, exFAT can refuse to duplicate 74 74 * the connection. VFS should then just make use of already existing phones and 75 75 * route its requests through them. To avoid paying the fibril creation price 76 * upon each request, FAT might want to keep the connections open after the76 * upon each request, exFAT might want to keep the connections open after the 77 77 * request has been completed. 78 78 */
