Check to see if allocation by kzalloc() or usb_alloc_urb() was unsuccessful immediately after the allocation. Exit from the function can be right at that point in case of allocation failure. This avoids unnecessary use of usb_alloc_urb() & usb_free_urb() if kzalloc() returns NULL. Also, makes the code better structured & easier to understand. Signed-off-by:

Using correct transfer interval as specified by the USB endpoint when doing the interrupt transfer fixes the warning printed by xhci USB core on every transfer that resulted in spamming "xhci_queue_intr_tx: 74 callbacks suppressed" to syslog every 5 seconds. Signed-off-by:

The timeout detection implemented in this driver isn't very robust. Although the USB interrupt transfer was successful, the polling thread often reported timeouts because the 50ms had expired before it got scheduled, and the SD card wasn't detected. Increasing it to 100ms, as used in other places of this driver, makes it work. Signed-off-by:

This patch checks the number of bulk I/O RPC pages with PTLRPC_MAX_BRW_PAGES in ofd_preprw() to avoid LASSERT(iobuf->dr_npages < iobuf->dr_max_pages) occurring while larger I/O size is specified. The patch also fixes echo_client_prep_commit() to reuse the env context so as to avoid LASSERT(info->fti_exp == NULL) occurring while the bulk I/O size is larger than PTLRPC_MAX_BRW_SIZE. The patch also improves obdfilter-survey to handle the case while interoprating with old server.

To make atime update properly between 1.8 client and 2.x server, this patch includes the following fixes: - if MDS_ATTR_xTIME is set without MDS_ATTR_xTIME_SET and the client does not have OBD_CONNECT_FULL20, convert it to LA_xTIME in mdt_setattr_unpack(). - set both MDS_ATTR_xTIME | MDS_ATTR_xTIME_SET for timestamps in ll_prepare_close(). This allows us to fix the server-side timestamp setting in the future. - remove attr_unpack() and convert the flags from MDS_ATTR_ to LA_* directly in mdt_attr_valid_xlate() instead. - improve sanityn.sh test_23().

Fix the CL_LAYOUT comment, since it is possible that layout swap could be used in cases where the file content is changed. I don't think there are any real world use cases for this, but that depends on what tools are being used on the filesystem.

Data corruption is possible if cp(coreutils) uses FIEMAP to obtain data holes in shared file, since there could be dirty cache on other clients which hasn't been flushed back. To ensure all the dirty on remote clients being flushed back on fiemap ioctl, we'd acquire ldlm lock on server side for fiemap, unless the local client (which invoke fiemap) has cached lock.

In order to avoid compatibility issues with older ChangeLog consumers, change the new CL_LAYOUT record to use the value previously assigned to CL_IOCTL. The CL_IOCTL type was never used anywhere, and it didn't really make any sense as a ChangeLog record, since it could really mean anything at all. The changelog_show_cb() function is renamed to changelog_kkuc_cb(), since it is really about consuming the ChangeLog and passing it up to the kernel-user-coms interface. At some point we should consider to implement a DBUS-based ChangeLog interface as well. The changelog_kkuc_cb() "sanity check" on cr_type was removed, since there is no reason the client kernel needs to know every record type that is being passed to userspace. It is up to the client tool to determine what records that it can process. Intel-bug-id: https://jira.hpdd.intel.com/browse/LU-3279 Lustre-change: http://review.whamcloud.com/6308Signed-off-by:
