[Ocfs2-devel] [PATCH 1/1] OCFS2: 64-bit inode number for getattr() instead of 32-bit value

[wengang wang]

ocfs2_getattr() uses generic_fillattr() to set inode number(and other
attributes). generic_fillattr() inturn fills inode number with inode->i_ino
which is a 32-bit(unsigned long) value.

if the ocfs2 partition is huge enough, that may become an incorrect
value.
the fix is filling it again after generic_fillattr() with ip_blkno(u64).
