Data movement within a computing environment is at the very least reduced. Data
is transmitted between a file system of the computing environment and a transmission
medium of that environment. The transmission includes bypassing non-file system
buffers in performing the transmission. For example, when data is sent to the file
system to be written to one or more storage media, the file system swaps one or
more buffers of the file system with the one or more buffers containing the data.
The swapping does not require the copying of data. Further, for a read operation,
the file system calls a routine, which is provided with one or more pointers to
the data that is to be sent to a requester of the data.
