Subject: MD RAID10: Export md_raid10_congested
X-Git-Tag: v3.6-rc1~21^2~10
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cc4d1efdd017083bbcbaf23feb4cdc717fa7dab8;p=pandora-kernel.git

MD RAID10: Export md_raid10_congested

md/raid10: Export is_congested test.

In similar fashion to commits
	11d8a6e3719519fbc0e2c9d61b6fa931b84bf813
	1ed7242e591af7e233234d483f12d33818b189d9
we export the RAID10 congestion checking function so that dm-raid.c can
make use of it and make use of the personality.  The 'queue' and 'gendisk'
structures will not be available to the MD code when device-mapper sets
up the device, so we conditionalize access to these fields also.
