[PATCH] ext3: ext3_symlink should use GFP_NOFS allocations inside
This patch fixes illegal __GFP_FS allocation inside ext3 transaction in
ext3_symlink(). Such allocation may re-enter ext3 code from
try_to_free_pages. But JBD/ext3 code keeps a pointer to current journal
handle in task_struct and, hence, is not reentrable.
This bug led to "Assertion failure in journal_dirty_metadata()" messages.
