| * | Adding ZERO_PAGE detection | Brian Atkinson | 2022-03-14 | 1 | -0/+27 |
| On some architectures ZERO_PAGE is unavailable because it references a GPL exported symbol of empty_zero_page. Originally e08b993 removed the call to PAGE_ZERO(0) for assignment to the abd_zero_page. However, a simple check can be done to avoid a kernel allocation and free for the abd_zero_page if ZERO_PAGE is available. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Brian Atkinson <[email protected]> Closes #13199 | |||||
