Subject: Suppress 'zfs_sb_create' memory warning
X-Git-Url: https://git.camperquake.de/gitweb.cgi?a=commitdiff_plain;ds=inline;h=bafc4e9e2ac3b4783a598afb1d2f048ab30c903c;p=zfs.git

Suppress 'zfs_sb_create' memory warning

When mutex debugging is enabled in your kernel the increased
size of the mutex structures can push the zfs_sb_t type beyond
the 8k warning threshold.  This isn't harmful so we suppress
the warning for this case.

Closes #628
