size = NOTE: in a 32bit arch with a preemptable kernel and* an UP compile the i_size_read/write must be atomic* with respect to the local cpu (unlike with preempt disabled),* but they don't need to be atomic with respect to other cpus like in* true SMP (so they

If PageUptodate(page) Then Return

BUG_ON( Our offset within mapping. )

233

BUG_ON(size > PAGE_SIZE - offset_in_page(inline_data))

addr = kmap_atomic(page)

236

memcpy(addr, inline_data, size)

237

memset(addr + size, 0, PAGE_SIZE - size)

238

Prevent people trying to call kunmap_atomic() as if it were kunmap()* kunmap_atomic() should get the return value of kmap_atomic, not the page.(addr)
