Re: [PATCH e2fsprogs] - ignore bind mounts in fsck

[Theodore Tso <tytso@mit.edu>]

This is what I actually committed into e2fsprogs git, in the maint
branch.  Note the one-line summary at the beginning of the patch
description, and the Addresses-Red-Hat-Bugzilla line before the
Signed-off-by lines.

    fsck: Ignore /etc/fstab entries for bind mounts
    
    If a user specifies a bind mount with a non-zero fsck pass number, for
    example:
    
    /foo    /bar    ext3    bind,defaults   1 3
    
    print a warning and ignore the fstab entry.
