.SH "DESCRIPTION"
.PP
.PP
This is the slow, transforming version for filesystems which do not
implement the address space operations prepare_write and commit_write.  It
uses the write file operation which should be present on all writeable
filesystems.
.PP
Using fops->write is slower than using aops->{prepare,commit}_write in the
transforming case because we need to double buffer the data as we cannot do
the transformations in place as we do not have direct access to the
destination pages of the backing file.
