If we think we're going to need to repair either the root directory or the lost+found directory, reserve a block at the end of pass 1 to reduce the likelihood of an e2fsck abort while reconstructing root/lost+found during pass 3. If / and/or /lost+found are corrupt and duplicate processing in pass 1b allocates all the free blocks in the FS, fsck aborts with an unusable FS since pass 3 can't recreate / or /lost+found. If either of those directories are missing, an admin can't easily mount the FS and access the directory tree to move files off the injured FS and free up space; this in turn prevents subsequent runs of e2fsck from being able to continue repairs of the FS. (One could migrate files manually with debugfs without the help of path names, but it seems easier if users can simply mount the FS and use regular FS management tools.) [ Fixed up an obvious C trap: const char * and const char [] are not the same thing when you are taking the size of the parameter. People, run your regression tests!
