Re: [PATCH] Fix dump_fs mount point detection and fallback mount

Simplify the code and fix mount point detection. The code logic is now much simpler: if $1 is not a mount point, call "mount --target $1" again to try mount it. "mount --target" cmd itself can handle all the /etc/fstab parsing job, so drop the buggy and complex bash code.
