NTFS: - Fix bug in fs/ntfs/attrib.c::ntfs_find_vcn_nolock() where after
dropping the read lock and taking the write lock we were not checking whether someone else did not already do the work we wanted to do. - Rename ntfs_find_vcn_nolock() to ntfs_attr_find_vcn_nolock(). - Tidy up some comments in fs/ntfs/runlist.c. - Add LCN_ENOMEM and LCN_EIO definitions to fs/ntfs/runlist.h. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
