rtm 17e3cf15ba fix iget() bug that allocated in-use inode[] entries 2006-08-13 15:51:58 +00:00
rtm 211ff0c67e namei returns locked parent dir inode for create / unlink
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

rtm 5be0039ce9 interrupts could be recursive since lapic_eoi() called before rti
so fast interrupts overflow the kernel stack
fix: cli() before lapic_eoi()

rsc 51716a869c Rename fd_reference to more suggestive fd_incref.
(Fd_reference sounds like it might just return the ref count.)
