2016-09-19staging: lustre: clio: rename coo_attr_set to coo_attr_updateBobi Jam10-32/+34
coo_attr_set() is used to update object's attribute but its name makes confusion that people intuitively think that it is used to pass object's attribute down to server sides.

2016-09-19staging: lustre: llite: pack suppgid to MDS correctlyFan Yong2-2/+35
The ll_lookup_it() may trigger IT_OPEN RPC to open a file by name. But at that time, the client does not know the target file's GID, so it cannot pack the necessary supplementary group ID in the RPC. Because of missing the supplementary group ID, the RPC maybe fail for open permission check on the MDS. Under such case, MDS should return the target file's GID, if the current thread on the client in the right group (according to the file's GID), the client will try the IT_OPEN RPC again with the right supplementary group ID. This patch is also helpful if some other(s) changed the file's GID after current RPC sent to the MDS with the suppgid as the original GID by race.

2016-09-19staging: lustre: ldlm: revert the changes for lock canceling policyJinshan Xiong1-6/+0
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.

2016-09-19staging: lustre: recovery: don't replay closed openNiu Yawei1-1/+5
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.

2016-09-19staging: lustre: replace direct HZ access with kernel APIsJian Yu6-12/+18
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.

Calculate the max easize by ld_active_tgt_count instead of ld_tgt_count. However this may introduce problems when the OSTs are in recovery because non sufficient buffer may be allocated to store EA.
