[PATCH] ufs: directory and page cache: install aops
This series of patches finished "bugs fixing" mentioned here http://lkml.org/lkml/2006/1/31/275 . The main bugs: * for i in `seq 1 1000`; do touch $i; done - crash system * mkdir create directory without "." and ".." entries The suggested solution is work with page cache instead of straight work with blocks. Such solution has following advantages * reduce code size and its complexity * some global locks go away * fix bugs The most part of code is stolen from ext2, because of it has similar directory structure. Patches testes with UFS1 and UFS2 file systems. This patch installs i_mapping->a_ops for directory inodes and removes some duplicated code.
