Subject: ext4: Use ext4_discard_reservations instead of mballoc-specific call
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=88aa3cff4e9a38b953de9fbc54c96e619a2bb9f9;p=firefly-linux-kernel-4.4.55.git

ext4: Use ext4_discard_reservations instead of mballoc-specific call

In ext4_ext_truncate(), we should use the more generic
ext4_discard_reservations() call so we do the right thing when the
filesystem is mounted with the nomballoc option.
