SET_DMA_RESERVE(9) Memory Management in Linux SET_DMA_RESERVE(9)NAME
set_dma_reserve - set the specified number of pages reserved in the first zone
SYNOPSIS
void set_dma_reserve(unsigned long new_dma_reserve);
ARGUMENTS
new_dma_reserve
The number of pages to mark reserved
DESCRIPTION
The per-cpu batchsize and zone watermarks are determined by present_pages. In the DMA zone, a significant percentage may be consumed by
kernel image and other unfreeable allocations which can skew the watermarks badly. This function may optionally be used to account for
unfreeable pages in the first zone (e.g., ZONE_DMA). The effect will be lower watermarks and smaller per-cpu batchsize.

nbp_name - NBP name parsing
SYNOPSIS
nbp_name( name, obj, type, zone )
char *name, **obj, **type, **zone;
DESCRIPTION
nbp_name() parses user supplied names into their component object, type, and zone. obj, type, and zone should be passed by reference, and
should point to the caller's default values. nbp_name() will change the pointers to the parsed-out values. name is of the form
object:type@zone, where each of object, :type, and @zone replace obj, type, and zone, respectively. type must be proceeded by `:', and
zone must be preceded by `@'.
EXAMPLE
The argument of afpd(8)'s -n option is parsed with nbp_name(). The default value of obj is the first component of the machine's hostname
(as returned by gethostbyname(3)). The default value of type is ``AFPServer'', and of zone is ``*'', the default zone. To cause afpd to
register itself in some zone other than the default, one would invoke it as
afpd -n @some-other-zone
obj and type would retain their default values.
BUGS
obj, type, and zone return pointers into static area which may be over-written on each call.

I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.
