below patch fixes a problem with symlinks where the target string had exactly
59 chars and the needed terminating null character.
(where the problem hits: when a fs with such entries gets checked by e2fsck
then those tool detects it as a problem and offers to delete that symlink.
if running an automated fixing cycle it would kill me all those symlinks.)
regards, Alex.
PS: in a test bed with a generated image file i am further seeing a note from
e2fsck about a fs with revision zero but feature flags are set.
thats reported as a fs problem and a fix is suggested by a y/n query.
