block: fix mismerge of the DISK_EVENT_MEDIA_CHANGE removal
Jens' back-merge commit 698567f3fa79 ("Merge commit 'v2.6.39' into
for-2.6.40/core") was incorrectly done, and re-introduced the
DISK_EVENT_MEDIA_CHANGE lines that had been removed earlier in commits
- 9fd097b14918 ("block: unexport DISK_EVENT_MEDIA_CHANGE for
legacy/fringe drivers")
- 7eec77a1816a ("ide: unexport DISK_EVENT_MEDIA_CHANGE for ide-gd
and ide-cd")
because of conflicts with the "g->flags" updates near-by by commit
d4dc210f69bc ("block: don't block events on excl write for non-optical
devices")
As a result, we re-introduced the hanging behavior due to infinite disk
media change reports.
Tssk, tssk, people! Don't do back-merges at all, and *definitely* don't
do them to hide merge conflicts from me - especially as I'm likely
better at merging them than you are, since I do so many merges.
