[dm-devel] [PATCH 0/9] Add protocol specific config subsection

[Benjamin Marzinski]

Some storage arrays can be accessed using multiple protocols at the same
time.  I've have customers request the ability to set different values
for the path specific timeouts, like fast_io_fail_tmo, based on the
protocol used to access the path. In order to make this possible, this
patchset adds a new protocol subsection to the device subsection and the
overrides section. This allows users to set a device config's path
specific timeouts, such as dev_loss_tmo, fast_io_fail_tmo, and
eh_deadline on a per-protocol basis.

Benjamin Marzinski (9):
  libmultipath: steal the src string pointer in merge_str()
  libmultipath: make protocol_name global
  libmultipath: add a protocol subsection to multipath.conf
  libmultipath: Set the scsi timeout parameters by path
  libmultipath: check the hwentry pctable for path variables
  libmultipath: make snprint_pctable indent a variable amount
  libmultipath: add procotol subsection to overrides
  libmultipath: fix eh_deadline documentation
  libmultipath: Add documentation for the protocol subsection
