Module Name:    src

Modified Files:
        src/sys/external/bsd/drm2/linux: linux_idr.c

Log Message:
Tweak slightly sketchy logic in linux_idr.

1. idr_preload can fail if you don't set __GFP_WAIT.
2. If idr_preload fails, it is wrong for idr_alloc to assert.
3. There is no way for idr_alloc to know what flags idr_preload got.

Probably won't *fix* any bugs, but if there is a bug with a missing
__GFP_WAIT, then we will learn about a trifle sooner.
