NAME
bitmap_parse_user - convert an ASCII hex string in a user buffer into a bitmapSYNOPSIS
- int bitmap_parse_user(const char __user * ubuf, unsigned int ulen, unsigned long * maskp, int nmaskbits);
ARGUMENTS
ubuf
- pointer 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_parse, 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.
