Switch from MIN to min and fix the new type warning. The
warning is produced because a comparison between iov_len,
which is a __kernel_size_t, is made to kiov_len, which is an
unsigned int (include/linux/lnet/types.h). Fix the warning
by casting kiov_len to __kernel_size_t.

Custom MIN/MAX operations are being used which are not as robust
as the built in min/max operations which will warn about potentially
problematic type comparisons.
For the simple cases, where no type warning is produced, simply
replace MIN/MAX with min/max.

of bytes not copied instead of -EFAULT.
2) The user could trigger a memory leak if the condition
"(hdr.ioc_len != data->ioc_len)" was true. Instead of adding a new call
to OBD_FREE_LARGE(), I created a free_buf label and changed everything
to use that label.

The `mult' parameter is negated if the user data begins with a '-' so
that the final value has the appropriate sign. But `mult' is only used
if the user data does not include a "units" suffix. In this case,
`mult' is overridden with the numeric scale conveyed by the units suffix,
but retains the sign of the original value.
Having `mult' serving double-duty works but is confusing. Use a new
local variable to store the sign of the user data instead. This also
fixes a pitfall of passing 0 to `mult', expecting it to be ignored when
a units suffix is specified, but having the effect of taking the
absolute value of the user-provided data.

with a define LUSTRE_MDT_MAXNAMELEN.

This patch fix a sparse warning in lustre sources
warning: incorrect type in argument 1 (different address spaces)
expected void [noderef] <asn:1>*to
got char *<noident>
This is done by adding the missing __user attribute on userland pointers inside the LPROC_SEQ_FOPS like macros:
- LPROC_SEQ_FOPS
- LPROC_SEQ_FOPS_RW_TYPE
- LPROC_SEQ_FOPS_WR_ONLY
- LDLM_POOL_PROC_WRITER
The patch also updates all the functions that are used by this macro:
- lprocfs_wr_*
- *_seq_write
as well as some helpers used by the previously modified functions (otherwise fixing the sparse warning add some new ones):
- lprocfs_write_frac_helper
- lprocfs_write_helper
- lprocfs_write_u64_helper
The patch also fixes one __user pointer direct dereference by strncmp in function fld_proc_hash_seq_write.

The dma->size calculations are overly complicated in this driver and the
'prealloc_bufsz' sanity checks are unnecessary.
Currently this driver determines the number of DMA "runs" needed and the size
of the "last" DMA transfer in order to perform a command. As long as there are
more "runs" required, the dma->size is set to the buffer maxsize. On the last
"run" the buffer is set to the "last" size.
Refactor the driver to use the comedi core helpers to determine the DMA size
based on the buffer maxsize and the number of samples remaining in the command.
This allows removing the 'dma_runs_to_end' and 'last_dma_run' mamebers from
the private data.
