From: Raphael S. Carvalho <raphael.scarv at gmail.com> Change since v1: * Fix bug on dentry structure (thank you specification; btw, sarcasm), and consequently a bug on ufs_readdir. * Add readlink support (applied tests for symlinks whose destionation path were stored in blk pointers and the file itself). * Several improvements. Wrote the documentation below. I think it would be good to
