Subject: btrfs: convert insert_inline_extent() to use a folio
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=c86d3aac8146ea5df911a037b9cf32881783d4e9;p=linux.git

btrfs: convert insert_inline_extent() to use a folio

We only use a page to copy in the data for the inline extent.  Use a
folio for this instead.
