This terminal 1-length variable array can be directly converted into a C99
flexible array member.
As all users of MPI2_CONFIG_PAGE_RAID_VOL_0 (Mpi2RaidVolPage0_t) either
calculate its size without depending on its sizeof() or do not use
PhysDisk[], no further source changes are required:
- mpt3sas_config.c:mpt3sas_config_get_number_pds() fetches a
Mpi2RaidVolPage0_t for itself, but does not use PhysDisk[].
- mpt3sas_config.c:mpt3sas_config_get_raid_volume_pg0() fetches a
Mpi2RaidVolPage0_t into a caller-provided buffer, and may fetch and
write PhysDisk[] into that buffer depending on its sz argument. Its
callers:
- mpt3sas_scsih.c:scsih_get_resync(),
mpt3sas_scsih.c:scsih_get_state(),
mpt3sas_scsih.c:_scsih_search_responding_raid_devices(), and
mpt3sas_scsih.c:_scsih_scan_for_devices_after_reset() all pass
sizeof(Mpi2RaidVolPage0_t) as sz, but do not use PhysDisk[].
- mpt3sas_scsih.c:_scsih_get_volume_capabilities() and
mpt3sas_warpdrive.c:mpt3sas_init_warpdrive_properties()
both calculate sz independently of sizeof(Mpi2RaidVolPage0_t)
and allocate a suitable buffer before calling
mpt3sas_config_get_raid_volume_pg0() and using PhysDisk[].

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.
