Since the log file name contains the current time in seconds, dumping the logs more than once per second causes EEXIST errors to be emitted. Add a static variable to libcfs_debug_dumplog_internal that records the time of the last Lustre log dump. If the current time in seconds is equal to the last time, do not dump logs again. Note that this is not thread-safe. However, in the rare case that two threads try to access last_dump_time simultaneously, the worst thing that could happen is that one of the threads will get an EEXIST error when trying to write the log file. This is no worse than the current situation, and it is not likely to happen. Signed-off-by:

Add client support to migrate the individual inodes from one MDT to another MDT, and this functionality will only migrate inode layout on MDT but not touch data object on OST. The directory will be migrated from top to the bottom, i.e. migrating parent first, then migrating the child. Signed-off-by:

There was no protection when inc/dec lu_device_type::ldt_device_nr, which may caused the ldt_device_nr to be wrong and trigger assert. This patch redefine lu_device_type::ldt_device_nr as atomic type. There was no protection when add/del lu_device_type::ldt_linkage into/from the global lu_device_types list, which may caused bad address accessing. This patch uses the existing obd_types_lock to protect related operations. We do NOT need lu_types_stop() any longer. Such function scans the global lu_device_types list, and for each type item on it which has zerod lu_device_type::ldt_device_nr, call its stop() method. In fact, the lu_device_type::ldt_device_nr only will be zero when the last lu_device_fini() is called, and at that time, inside the lu_device_fini(), its stop() method will be called. So it is unnecessary to call the stop() again via lu_types_stop(). Signed-off-by:

This patch handles the upgrade situation that old mountdata already contains comma-separated NIDs. The correct way to fix the original issue is to parse comma-separated NIDs in lmd_parse(). Signed-off-by:

Add delete striped directory, it includes 1. enable sync log between MDTs, so slave objects will be delete by unlink log, which is similar as deleting ost object. 2. retrieve layout information of striped directory on MDT, then lock all of the slave objects before unlink. Signed-off-by:

1. client send create request to the master MDT, which will allocate FIDs and create slaves. for all of slaves. 2. Client needs to revalidate slaves during intent getattr and open request. 3. lmv_stripe_md will include attributes(size, nlink etc) from all of stripe, which will be protected by UPDATE lock. client needs to merge these attributes when update inode. 4. send create request to the MDT where the file is located, which can help creating master stripe of striped directory.

wang di authored
The lmv_[un]pack_md function are used to calculate the size of the data used to represent the LMV striping data. The original code was straight forward in its calculate with lmv_get_easize since only one type of data format could exist. We want to be able to support different version of this data in the future so this patch moves to generating the size of the data using the stripe count and which LMV_MAGIC_* version. Signed-off-by:

Ensure we properly lock between visorinput_channel_interrupt(), visorinput_open(), and devdata_create(). We now guarantee that: * interrupts will be disabled and remain disabled during device creation, by setting 'paused = true' across device creation * we canNOT get into visorinput_open() until the device structure is totally initialized, by delaying the input_register_device() until the end of device initialization We also now ensure that lock_visor_dev is held across updates of devdata state, to ensure state consistency.

When this functionality was first implemented, visorchipset and visorbus were separate drivers, which necessitated a registration mechanism for them to communicate. More-recently, visorchipset and visorbus were combined into a single driver, and now exist as separate source files within the same driver, known as 'visorbus'. This eliminated the need for a registration mechanism, but it has remained nevertheless until now. For the sake of simplification, this registration mechanism is now being removed. Signed-off-by:
