Subject: mm/memory-failure: replace magic number 3 with GET_PAGE_MAX_RETRY_NUM
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c70a9f639bfd662b95b5e3e64f4b62b13c237eca;p=thirdparty%2Fkernel%2Flinux.git

mm/memory-failure: replace magic number 3 with GET_PAGE_MAX_RETRY_NUM

Replace the hardcoded magic number 3 in get_any_page() with the existing
GET_PAGE_MAX_RETRY_NUM macro for code consistency and maintainability.

This change has no functional impact, only improves code readability and
unifies the retry limit configuration.
