X-Git-Tag: v2.6.31-rc1~390^2~22 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=48bf2b1711dc498494e77705c415ee46bb508fd9;p=pandora-kernel.git GFS2: Something nonlinear this way comes! For some reason GFS2 has been missing support for non-linear mappings. This patch fixes that, and also avoids taking any locks for mmap in the O_NOATIME case. In fact we don't actually need to take the lock here at all - just doing file_accessed() would be enough, but we have to take the lock eventually and this helps it hit disk (and thus be seen by other nodes) faster.
