![]() * make ext2_new_inode() put the inode into icache in locked state * do not unlock until the inode is fully set up; otherwise nfsd might pick it in half-baked state. * make sure that ext2_new_inode() does *not* lead to two inodes with the same inumber hashed at the same time; otherwise a bogus fhandle coming from nfsd might race with inode creation: nfsd: iget_locked() creates inode nfsd: try to read from disk, block on that. ext2_new_inode(): allocate inode with that inumber ext2_new_inode(): insert it into icache, set it up and dirty ext2_write_inode(): get the relevant part of inode table in cache, set the entry for our inode (and start writing to disk) nfsd: get CPU again, look into inode table, see nice and sane on-disk inode, set the in-core inode from it oops - we have two in-core inodes with the same inumber live in icache, both used for IO.
