Subject: [PATCH 1/2] ext4: Remove arbitrary block value in __es_remove_extent()
In __es_remove_extent() we're storing seemingly arbitrary value
0x7FDEADBEEF into block variable. I assume that the reason is just to
initialize the variable before the use because the actual value does not
matter at this point.
Just remove the arbitrary value and initialized block variable to zero
which is much less suspicious.
