Subject: btrfs: set fs_devices->seed directly
X-Git-Tag: v4.19~1424^2~131
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=71f8a8d2c1ee65589b3f0ec5f2306723ea76c1ee;p=platform%2Fkernel%2Flinux-rpi3.git

btrfs: set fs_devices->seed directly

This is in preparation to move a section of code in __btrfs_open_devices()
into a new function so that it can be reused. As we set seeding if any of
the device is having SB flag BTRFS_SUPER_FLAG_SEEDING, so do it in the
device list loop itself. No functional changes.
