Some proc parameters were moved from ofd to osd module and only their symlinks were kept in ofd for interoperability/compatibility. To process this kind of config params passed by ofd, this patch is to do the following fixes: - since these parameters are not included by the static lprocfs var list, a pre-check is added for them to avoid "unknown param" error message confuses the uses. If they are matched in this check, they will be passed to the osd directly. - improve the error messages in class_process_proc_param() and class_process_proc_seq_param() a little.

2016-04-28staging: lustre: osc: Use SOFT_SYNC to urge server commitPrakash Surya
This change adds a BRW page flag, OBD_BRW_SOFT_SYNC. This flag is intended to urge a server to commit a client's unstable pages to stable storage. A client will add this flag to any BRW requests while it is in a state where it has "many" unstable pages pinned in its cache. The server, upon receiving a page with this flag set, *should* begin an async commit. The idea being that, with the proactive async commit, the client's pinned unstable pages will transition into a stable state faster than they would have otherwise. Although, the server side portion of this agreement is still unimplemented, so the OBD_BRW_SOFT_SYNC flag will currently fall on deaf ears.

2016-04-28staging: lustre: osc: Track number of "unstable" pages per oscPrakash Surya
This change adds simple accounting hooks for "unstable" pages on a per OSC basis. Now, in addition to the per filesystem tracking, each OSC will maintain a running total of its unstable pages. These counters are exported through the proc interface, and can be read using the lctl command. For example: # Read number of unstable pages contained by each OSC lctl get_param osc.*.unstable_stats The motivation for this change is in anticipation of implementing a "soft sync" functionality, urging servers to commit these unstable pages to stable storage. The per OSC accounting allows a client to limit the soft sync request to only the OSCs which have outstanding unstable pages.

2016-04-28staging: lustre: osc: Track and limit "unstable" pagesPrakash Surya
This change adds a global counter to track the number of "unstable" pages held by a given client, along with per file system counters. An "unstable" page is defined as a page which has been sent to the server as part of a bulk request, but is uncommitted to stable storage. In addition to simply tracking the unstable pages, they now also count towards the maximum number of "pinned" pages on the system at any given time. Thus, a client will now be bound on the number of dirty and unstable pages it can pin in memory. Previously only dirty pages were accounted for in this limit. In addition to tracking the number of unstable pages in Lustre, the NR_UNSTABLE_NFS memory zone is also incremented and decremented for easy monitoring using the "NFS_Unstable:" field in /proc/meminfo. This field is also used internally by the kernel to limit the total amount of unstable pages on the system. The motivation for this change is twofold. First, the client must not allow itself to disconnect from an OST while still holding unstable pages. Otherwise, these unstable pages can get lost due to an OST failure, and replay is not possible due to the disconnect via unmount. Secondly, the client needs a mechanism to prevent it from allocating too much of its available RAM to unreclaimable pages pinned by the ptlrpc layer. If this case occurs, out of memory events can trigger as a side effect, which we need to avoid. The current number of unstable pages accounted for on a per file system granularity is exported by the unstable_stats proc file, contained under each file system's llite namespace. An example of retrieving this information is below: $ lctl get_param llite.*.unstable_stats Signed-off-by: Prakash Surya <surya1@llnl.gov> Intel-bug-id: https://jira.hpdd.intel.com/browse/LU-2139 Reviewed-on: http://review.whamcloud.com/6284 Reviewed-by: Jinshan Xiong <jinshan.xiong@intel.com> Reviewed-by: Andreas Dilger <andreas.dilger@intel.com> Reviewed-by: Oleg Drokin <oleg.drokin@intel.com> Signed-off-by: James Simmons <jsimmons@infradead.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2016-04-28staging: lustre: llite: Replace printing of i_ino with ll_inode2fid()James Nunez
The printing of i_ino/i_generation in llite messages is not nearly so useful as printing the full inode FID, since i_ino is a "compressed" version of the FID and there may be duplicate values for i_ino in some cases (especially if running on a 32-bit client). All instances of printing i_ino/i_generation are replaced with the FID using ll_inode2fid(). All instances, except for one, of printing just i_ino was replaced by printing the FID. In all CERROR lines touched by the i_ino replacements, the device name or fsname was added at the beginning of the message if it did not already exist.

2016-04-28staging: lustre: ldlm: remove code wireshark handlingBruce Korb
Wireshark output moved to userland file "lustre_dlm_flags_wshark.c" and only bits that can actually appear "on the wire" are emitted. The user land "packet-lustre.c" code that references these bits now gets emitted into that file. e.g. the "local_only" bit is never put on the wire, so references to it in wireshark are gone.

2016-04-28staging: lustre: ldlm: clean up l_flagsBruce Korb
Remove the now obsolete LDLM_AST_FLAGS and LDLM_INHERIT_FLAGS defines. Remove the obsolete LDLM_FL_HIDE_LOCK_MASK define. Rename "local_only" mask to "off_wire" since it is confusingly similar to a flag that (I think) means, "do not copy this lock over the wire."

2016-04-28staging: lustre: ldlm: use accessor macros for l_flagsBruce Korb
Convert most of the ldlm lock's l_flags references from direct bit twiddling to using bit specific macros. A few multi-bit operations are left as an exercise for the reader. The changes are mostly in ldlm, but also in llite, osc and quota. Also add a multi-bit (mask) test.
