Add store capability to the rport port_state using sysfs under fc_remote_ports/rport-*/port_state. With this the user can move the port_state from Marginal->Online and Online->Marginal. - Marginal: This interface will set SCMD_NORETRIES_ABORT bit in scmd->state for all the pending I/Os on the SCSI device associated with target port. - Online: This interface will clear SCMD_NORETRIES_ABORT bit in scmd->state for all the pending I/Os on the SCSI device associated with target port. The following interface is provided to set the port state to Marginal and Online respectively: echo "Marginal" >> /sys/class/fc_remote_ports/rport-X\:Y-Z/port_state echo "Online" >> /sys/class/fc_remote_ports/rport-X\:Y-Z/port_state Link: https://lore.kernel.org/r/1609969748-17684-5-git-send-email-muneendra.kumar@broadcom.com Reviewed-by: Himanshu Madhani <himanshu.madhani@oracle.com> Reviewed-by: Ewan D.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
