While clients will resend client->server RPCs, servers would not resend server->client RPCs such as LDLM callbacks (blocking or completion callbacks/ASTs). This could result in clients being evicted from the server if blocking callbacks were dropped by the network (a failed router or lossy network) and the client did not cancel the requested lock in time. In order to fix this problem, this patch adds the ability to resend LDLM callbacks from the server and give the client a chance to respond within the timeout period before it is evicted: - resend BL AST within lock callback timeout period; - still do not resend CANCEL_ON_BLOCK; - regular resend for CP AST without BL AST embedded; - prolong lock callback timeout on resend; some fixes: - recovery-small test_10 to actually evict the client with dropped BL AST; - ETIMEDOUT to be returned if send limit is expired; Signed-off-by:

Statahead thread should wait for inflight stat RPCs to finish in case statahead RPC callback may access data allocated in statahead thread context. ll_sa_entry_fini() should keep old entry if stat RPC is not finished yet. Simplify sai refcounting: * newly allocated sai will hold one refcount, and it will put it after starting statahead thread. * statahead thread holds one refcount. * agl thread holds one refcount. * stat process calls do_statahead_enter() which will try to get sai, and if it's valid, it will revalidate from statahead cache, and put refcount after use.

Move the LUSTRE_VERSION_CODE checks to trigger on x.y.53 instead of x.y.50, so that it is into the development cycle that they are hit instead of right at the start. In many cases, the #warning has been removed (to prevent build errors) and instead the code is just disabled outright. The dead code can be seen easily and removed in the future with less interruption to the development process. Signed-off-by:

When a read ahead does not reach the end of the region reserved from ras, we'd set ras::ras_next_readahead back to where we left off; For stride read ahead, it needs to make sure that the offset is no less than ras_stride_offset, so that the stride read ahead can work correctly. Signed-off-by:

Define new constants LL_LEASE_{RD,WR,UN}LCK for use as the argument to and return value from the LL_IOC_{GET,SET}_LEASE ioctls. As arguments, these contants replace the use of F_{RD,WR,UN}LCK from fcntl.h. As return values they replace the use of FMODE_{READ,WRITE} which are internal to the Linux kernel source and not under the control of the Lustre ioctl interface. Signed-off-by: -

Umount process relies on lu_site_purge(-1) to purge all objects before umount, however, if there happen to have a cache shrinker which calls lu_site_purge(nr) in parallel, some objects may still being freed by cache shrinker even after the lu_site_purge(-1) called by umount done. This can be simply fixed by serializing purge threads, since it doesn't make any sense to have them in parallel. Signed-off-by:
