Subject: eCryptfs: increment extent_offset once per loop interation
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=778d1a2bd42ae862a6c6d20a1c3af5e45b3c1924;p=linux-edison.git

eCryptfs: increment extent_offset once per loop interation

The extent_offset is getting incremented twice per loop iteration through any
given page.  It should only be getting incremented once.  This bug should only
impact hosts with >4K page sizes.
