[PATCH] fs: clean up __block_commit_write

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Function __block_commit_write did nothing with the inode passed in
and it always returned 0. This patch changes it to a void and gets
rid of the overhead needed to pass in the inode.
