Add comment blocks on lprocfs_stats_lock() and lprocfs_stats_unlock(). Move common NOPERCPU code out of the switch() statements to reduce code size and complexity, since it doesn't depend on the opc at all. Replace switch() in lprocfs_stats_unlock() with a simple if/else, since the lock opc was already checked in lprocfs_stats_lock(). Add an enum for the lprocfs_stats_lock() operations to make it clear what the valid values are and allow compiler checking. Signed-off-by:

Buggy code at ptlrpc_connect_interpret() finish: rc = ptlrpc_import_recovery_state_machine(imp); ... Set import connection flags When import has FULL state ptlrpc_import_recovery_state_machine() wakeup all waiters on import and all delayed request, which was resented. And it could happened that request was send without updated flags and AT is disabled. If such request is in progress on the server, server drop the new instance, and could do early reply for it. But this early reply confuse client, cause it wait real reply(no AT for this request). Client try to touch buffer outside reply and got EPROTO error. The same bug existed for initital connect too. Import became FULL before import connection flags was set.

Change return type and size argiments of lustre_msg_hdr_size(), lustre_msg_buf{len,count}() and req_capsule_*_size() to __u32. Change type of req_format->rf_idx and req_format->rf_fields.nr to size_t. Also return zero for incorrect message magic instead of -EINVAL. This will be more robust because of few of them after LASSERTF(0, "...") and will not be returned. In the rest places it return zero size instead of huge number after implicit unsigned conversion.

It may be that a client or MDS is trying to connect to a target (OST or peer MDT) before that target is finished setup. Rather than spamming the console logs during initial connection, only print a console error message if there are repeated failures trying to connect to the target, which may indicate an error on that node.

The changes for LRU lock policy was introduced by commit bfae5a4e, where I was trying to revise the policy to pick locks for canceling. However, this caused two problems as mentioned in LU-5727. The first problem is that the lock can only be picked for canceling only if the number of LRU locks is over preset LRU number AND it's aged; the second problem is that mdc_cancel_weight() tends to not cancel OPEN locks, therefore open locks can be kept forever and finally exhausts memory on the MDT side. The commit 7b2d26b0 ("revert changes to ldlm_cancel_aged_policy") fixed the first problem. This patch will revert the rest of changes related to LRU policy revise. Signed-off-by:

To avoid scanning the replay open list every time in the ptlrpc_free_committed(), the fix of LU-2613 (4322e0f9) changed the ptlrpc_free_committed() to skip the open list unless the import generation is changed. That introduced a race which could make a closed open being replayed: 1. Application calls ll_close_inode_openhandle()-> mdc_close(), to close file, rq_replay is cleared, but the open request is still on the imp_committed_list; 2. Before the md_clear_open_replay_data() is called for close, client start replay, and that closed open will be replayed mistakenly; 3. Open replay interpret callback (mdc_replay_open) could race with the mdc_clear_open_replay_data() at the end; This patch fix the ptlrpc_free_committed() to make sure the open list is scanned on recovery to prevent the closed open request from being replayed.

On some customer's systems, kernel was compiled with HZ defined to 100, instead of 1000. This improves performance for HPC applications. However, to use these systems with Lustre, customers have to re-build Lustre for the kernel because Lustre directly uses the defined constant HZ. Since kernel 2.6.21, some non-HZ dependent timing APIs become non- inline functions, which can be used in Lustre codes to replace the direct HZ access. These kernel APIs include: jiffies_to_msecs() jiffies_to_usecs() jiffies_to_timespec() msecs_to_jiffies() usecs_to_jiffies() timespec_to_jiffies() And here are some samples of the replacement: HZ -> msecs_to_jiffies(MSEC_PER_SEC) n * HZ -> msecs_to_jiffies(n * MSEC_PER_SEC) HZ / n -> msecs_to_jiffies(MSEC_PER_SEC / n) n / HZ -> jiffies_to_msecs(n) / MSEC_PER_SEC n / HZ * 1000 -> jiffies_to_msecs(n) This patch replaces the direct HZ access in lustre modules.
