/*
* Return the offset into page `page_nr' of the last valid
* byte in that page, plus one.
*/
static unsigned
ext2_last_byte(struct inode *inode, unsigned long page_nr)
{
unsigned last_byte = inode->i_size;
last_byte -= page_nr << PAGE_CACHE_SHIFT;
if (last_byte > PAGE_CACHE_SIZE)
last_byte = PAGE_CACHE_SIZE;
return last_byte;
}
tht's a small function to get last byte of page number page_nr
but it seems to be wrong
as
last byte of page_nr if byte number start with 0 for page_nr 1
last_byte should be = page_nr * (2^12 )
why its been subtracted from total size i_size?????
pl tell me what i am missing ?
