In Lustre 2.4, the flags passed to the memory allocation functions are translated from CFS enumeration values types to the kernel GFP values by calling cfs_alloc_flags_to_gfp(). This function adds __GFP_WAIT to all flags except CFS_ALLOC_ATOMIC. In 2.5, when the cfs wrappers were dropped, cfs_alloc_flags_to_gfp() was removed and the CFS_ALLOC_xxxx was simply replaced with __GFP_xxxx. This means that most memory allocation calls are missing the __GFP_WAIT flag. The result is that Lustre experiences more ENOMEM errors, many of which the higher levels of Lustre do not handle robustly. Notes GFP_NOFS = __GFP_WAIT | __GFP_IO. So the patch replaces __GFP_IO with GFP_NOFS. Patch does not add __GFP_WAIT to GFP_IOFS. GFP_IOFS was not used in Lustre 2.4 so it has never been used with __GFP_WAIT. Signed-off-by:

If a connection has been stopped with ptlrpc_pinger_del_import() and marked obd_no_recov, don't reconnect in ptlrpc_disconnect_import() if the import is already disconnected. Otherwise, without the pinger it will just wait there indefinitely for the reconnection that will never happen. Put the obd_no_recov check inside ptlrpc_import_in_recovery() so that any threads waiting on the connection to recover would also be broken out of their sleep if obd_no_recov is set. Signed-off-by:

LNET messages that are dropped are not accounted for correctly in /proc/sys/lnet/stats. What I assume to be a simple typo is causing drop_length to be double-counted and drop_count to never be incremented. Signed-off-by:

lustre_get_emerg_rs() set the size of the reply buffer to zero by mistake, which will cause LBUG in null_alloc_rs() when memory pressure is high. This patch fix this problem and adds a size check to avoid the problem of insufficient buffer size. Signed-off-by:
