[PATCH 02/35] e2fsck: turn inline data symlink into a fast symlink when possible

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

 



When there's a problem accessing the EA part of an inline data symlink
and we want to truncate the symlink back to 60 characters (hoping the
user can re-establish the link later on, apparently) be sure to turn
off the inline data flag to convert the symlink back to a regular fast
symlink.
