ptlrpc is using rq_xid as matchbits of bulk data, which means it has to change rq_xid for bulk resend to avoid several bulk data landing into the same buffer from different resends. This patch uses one of reserved __u64 of ptlrpc_body to transfer mbits to peer, matchbits is now separated from xid. With this change, ptlrpc can keep rq_xid unchanged on resend, it only updates matchbits for bulk data. This protocol change is only applied if both sides of connection have OBD_CONNECT_BULK_MBITS, otherwise, ptlrpc still uses old approach and update xid while resending bulk. Signed-off-by:

If you create a file, archive and release it, it keeps only a link and all information in xattr. If you tar the file with --xattr you will store the same striping information and link information in the tar. If you delete the file, the file and archive state does not make sense. Now if you restore the file using tar with xattr having the RELEASED flag turned on, then it is not correct because this is a new file. Hence ignoring the HSM xattr and masking out the "RELEASED" flag for the files, which are not archived. Signed-off-by:

Do not lookup master inode by ilookup5, instead it should use ilookup5_nowait, otherwise it will cause dead lock, 1. Client1 send chmod req to the MDT0, then on MDT0, it enqueues master and all of its slaves lock, (mdt_attr_set() ->mdt_lock_slaves()), after gets master and stripe0 lock, it will send the enqueue request(for stripe1) to MDT1, then MDT1 finds the lock has been granted to client2. Then MDT1 sends blocking ast to client2. 2. At the same time, client2 tries to unlink the striped dir (rm -rf striped_dir), and during lookup, it will hold the master inode of the striped directory, whose inode state is NEW, then tries to revalidate all of its slaves, (ll_prep_inode()->ll_iget()->ll_read_inode2()-> ll_update_inode().). And it will be blocked on the server side because of 1. 3. Then the client get the blocking_ast request, cancel the lock, but being blocked by ilookup5 in ll_md_blocking_ast(), because the inode state is still NEW. Signed-off-by:

If ll_iget fails during inode initialization, especially during striped directory lookup after creation failed, then it should clear stripe MD before make_bad_inode(), because make_bad_inode() will reset the i_mode, which can cause ll_clear_inode() skip freeing those stripe MD. Signed-off-by:

In some cases with a very long pathname, such as with sanity.sh test_154c, mdc_ioc_fid2path() would spew long debug messages to the log, because libcfs_debug_vmsg2() refuses to log messages over one page in size. Truncate the debug message to only log the last 512 characters of the pathname, which is sufficient for most debugging, saves a bit of space in the debug log, and will prevent the debug logging from printing to the console in the first place.

In this patch, osc_extent::oe_no_merge is introduced, and this flag is set if osc_extent submitted via osc_io_submit() includes partial pages.

The correct thing to > do is to use monotomic clock current value instead of the > wall clocks value when calculating recalc_interval_sec. This broke when I converted the 32-bit get_seconds() into ktime_get_{real_,}seconds() inconsistently. Either one of those two would have worked, but mixing them does not. Staying with the original intention of the patch, this changes the ktime_get_seconds() calls into ktime_get_real_seconds(), using real time instead of mononic time.

When lu_object_alloc() reaches to LOV object init, we need initialize its stripe type beforehand, so that if something wrong in the conf buffer, the object chain need to be traversed to free what has been allocated, with LOV object type be set as LLT_EMPTY, and when the LOV part is reached, it won't panic without knowing what stripe type it is. This patch also improves debug messages in lsm_unpackmd_common(), and does not return error if the LOV device is still processing config log while trying to verify a layout buffer. Signed-off-by:
