| Various changes made while offline. + bwrite sector argument is redundant; use b->sector. + reformatting of files for nicer PDF page breaks + distinguish between locked, unlocked inodes in type signatures + change FD_FILE to FD_INODE + move userinit (nee proc0init) to proc.c + move ROOTDEV to param.h + always parenthesize sizeof argument | |||||

| 2007-08-21 | Various cleanup: | rsc | 1 | -1/+7 | |
| - Got rid of dummy proc[0]. Now proc[0] is init. - Added initcode.S to exec /init, so that /init is just a regular binary. - Moved exec out of sysfile to exec.c - Moved code dealing with fs guts (like struct inode) from sysfile.c to fs.c. Code dealing with system call arguments stays in sysfile.c - Refactored directory routines in fs.c; should be simpler. - Changed iget to return *unlocked* inode structure. This solves the lookup-then-use race in namei without introducing deadlocks. It also enabled getting rid of the dummy proc[0]. | |||||

| don't hold fd table lock across idecref() (latter does block i/o) idecref calls iput() in case last ref -> freeing inode dir size is 512 * # blocks, so readi/writei &c work unlink deletes dirent even if ip->nlink > 0 | |||||
