[PATCH] e2fsprogs - e2fsck pass1c does extra work if root dir has shared blocks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Ted,

Another small bug I think: if the root directory contains shared blocks, e2fsck pass1c search_dirent_proc() will be looking for one more containing directory than it will ever find, and thus loses an opportunity to terminate early.
