Subject: btrfs: declare rsv_count as unsigned int instead of int
X-Git-Tag: firefly_0821_release~176^2~545^2~70^2~5

btrfs: declare rsv_count as unsigned int instead of int

rsv_count ultimately gets passed to start_transaction() which
now takes an unsigned int as its num_items parameter.
The value of rsv_count should always be positive so declare it
as being unsigned.
