Subject: iomap: remove the inode_dio_begin/end calls
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=refs%2Fheads%2Fi_rwsem-non_owner;p=users%2Fhch%2Fxfs.git

iomap: remove the inode_dio_begin/end calls

Now that all iomap users hold i_rwsem over asynchronous I/O
operations these calls can be removed.
