NTFS: 2.1.14 - Fix an NFSd caused deadlock reported by several users.
- Modify fs/ntfs/ntfs_readdir() to copy the index root attribute value
to a buffer so that we can put the search context and unmap the mft
record before calling the filldir() callback. We need to do this
because of NFSd which calls ->lookup() from its filldir callback()
and this causes NTFS to deadlock as ntfs_lookup() maps the mft record
of the directory and since ntfs_readdir() has got it mapped already
ntfs_lookup() deadlocks.
