happen is unclear however so it is worth waiting until someone hits
the problem.
+2.1.28 - Fix a deadlock.
+
+ - Fix deadlock in fs/ntfs/inode.c::ntfs_put_inode(). Thanks to Sergey
+ Vlasov for the report and detailed analysis of the deadlock. The fix
+ involved getting rid of ntfs_put_inode() altogether and hence NTFS no
+ longer has a ->put_inode super operation.

2.1.27 - Various bug fixes and cleanups.
- Fix two compiler warnings on Alpha. Thanks to Andrew Morton for
