Revision b4c5c60920e3b0c4598f43e7317559f6aec51531 authored by Minchan Kim on 23 July 2014, 21:00:04 UTC, committed by Linus Torvalds on 23 July 2014, 22:10:54 UTC
Sasha reported lockdep warning [1] introduced by [2].
It could be fixed by doing disk revalidation out of the init_lock. It's
okay because disk capacity change is protected by init_lock so that
revalidate_disk always sees up-to-date value so there is no race.

[2] zram: revalidate disk after capacity change
Fixes 2e32baea46ce ("zram: revalidate disk after capacity change").
