Al Viro b231509616 udf: fix the udf_iget() vs. udf_new_inode() races ... Currently udf_iget() (triggered by NFS) can race with udf_new_inode() leading to two inode structures with the same inode number: nfsd: iget_locked() creates inode nfsd: try to read from disk, block on that. udf_new_inode(): allocate inode with that inumber udf_new_inode(): insert it into icache, set it up and dirty udf_write_inode(): write inode into buffer cache nfsd: get CPU again, look into buffer cache, see nice and sane on-disk inode, set the in-core inode from it Fix the problem by putting inode into icache in locked state (I_NEW set) and unlocking it only after it's fully set up.
