Subject: [GFS2] Quotas non-functional - fix bug
X-Git-Tag: v2.6.23-rc1~1156^2~48
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2a87ab080607d009b8b2a8706f4e27d70402ca9c;p=linux-2.6

[GFS2] Quotas non-functional - fix bug

This patch fixes an error in the quota code where a 'struct
gfs2_quota_lvb*' was being passed to gfs2_adjust_quota() instead of a
'struct gfs2_quota_data*'. Also moved 'struct gfs2_quota_lvb' from
fs/gfs2/incore.h to include/linux/gfs2_ondisk.h as per Steve's suggestion.
