[Devel] [PATCH vz10 v3 02/11] ext4: remove unused datawriteback variable from ext4_sync_files

[Konstantin Khorenko]

From: Pavel Tikhomirov <ptikhomirov at virtuozzo.com>

The datawriteback variable was defined but never used after its assignment.
Remove both declaration and assignment to clean up the code.

Part of rework for ext4_sync_files function.

Fixes: 26337aacaafa9 ("ext4: add mfsync support")

Signed-off-by: Pavel Tikhomirov <ptikhomirov at virtuozzo.com>

Feature: ext4: optimized sync of a set of files - mfsync()
