The patch titled
git-block: more XFS fixes
has been removed from the -mm tree. Its filename was
git-block-more-xfs-fixes.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: git-block: more XFS fixes
From: Jens Axboe <[EMAIL PROTECTED]>
That down() probably wants a replug to precede it. Probably something
like:
if (atomic_read(&bp->b_io_remaining))
blk_replug_current_nested();
for xfs_buf_wait_unpin() and xfs_buf_lock(). Does this fix it?
