[e2fsprogs PATCH] e2fsck: don't allow journal inode to have encrypt flag

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

 



From: Eric Biggers <ebiggers@xxxxxxxxxx>

Since the kernel is being fixed to consider journal inodes with the
'encrypt' flag set to be invalid, also update e2fsck accordingly.
