 Description   

The commit 06a67987e06f7fa9c0bfde549d54e2bed0a78ade introduced server identifier into lu_seq_range to distinguish between MDT and OST fids. But for old 2.0 client, it did not specify such identifier/flags, then caused 'fld_server_lookup()' failure.

Comment by Andreas Dilger [ 07/Jun/11 ]

I can't understand how this change could have affected the network protocol. It renamed the "lsr_mdt" field to "lsr_index", and "lsr_padding" to "lsr_flags", and replaced a constant "0" with LU_SEQ_RANGE_MDT, which is defined as 0 itself.

Comment by nasf (Inactive) [ 07/Jun/11 ]

It should be, but the parameter of "res" for 'fld_server_lookup()' is allocated on stack, some fields, including "lsr_padding/lsr_flags" is not initialized, so the value of "lsr_flags" may be not zero.
