NAME¶
bitmap_parselist_user -SYNOPSIS¶
int
bitmap_parselist_user(const char __user * ubuf,
unsigned int ulen,
unsigned long * maskp,
int nmaskbits);
ARGUMENTS¶
ubufpointer to user buffer containing
string.
ulen
buffer size in bytes. If string is smaller
than this then it must be terminated with a \0.
maskp
pointer to bitmap array that will contain
result.
nmaskbits
size of bitmap, in bits.
DESCRIPTION¶
Wrapper for bitmap_parselist, providing it with user buffer. We cannot have this as an inline function in bitmap.h because it needs linux/uaccess.h to get the access_ok declaration and this causes cyclic dependencies.COPYRIGHT¶
