Vladislav Bolkhovitin 836481737a vdisk_blockio: Specify REQ_SYNC for synchronous I/O requests
Using READ_SYNC instead of READ increases the priority of read requests.
Using WRITE_SYNC instead of REQ_WRITE increases the priority of write
requests and avoids that the CFQ scheduler queues such writes waiting
for further write requests.

This is the SCST development repository. It contains not a single
project SCST as one can think, but a number of them, which are divided
as the following:

1. SCST core in scst/ subdirectory

2. Administration utility for SCST core scstadmin in scstadmin/

3. Target drivers in own subdirectories qla2x00t/, iscsi-scst/, etc.

4. User space programs in usr/ subdirectory, like fileio_tgt.

5. Some various docs in doc/ subdirectory.

Those subprojects are in most cases independent from each other,
although some of them depend from the SCST core. They put in the single
repository only to simplify their development, they are released
independently.

Thus, use "make all" only if you really need to build everything.
Otherwise build only what you need, like for iSCSI-SCST:

make scst scst_install iscsi iscsi_install

For more information about each subproject see their README files.
