Subject: ext4: enable DIOREAD_NOLOCK by default for BS > PS as well
X-Git-Tag: v6.19-rc1~161^2~20
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=58297412edf077870eedce2481db5755b4e98474;p=thirdparty%2Flinux.git

ext4: enable DIOREAD_NOLOCK by default for BS > PS as well

The dioread_nolock related processes already support large folio, so
dioread_nolock is enabled by default regardless of whether the blocksize
is less than, equal to, or greater than PAGE_SIZE.
