| | * | | | | | | | ceph: try to send partial cap release on cap message on missing inodeSage Weil2010-06-10

This keeps us from making the MDS wait when the cap release it needs is in a partially full release message. If we fail because of ENOMEM, oh well, they'll just have to wait a bit longer.

This patch makes sure we directly use one set of flags to deal with it, and use it consistently, which means: - always notify about completion from the rcu callback. We only ever wait for it from on-stack callers, so this simplification does not even cause a theoretical slowdown currently. It also makes sure we don't miss out on the notification if we ever add other callers to wait for it. - make earlier completion notification depending on the on-stack allocation, not the sync mode. If we introduce new callers that want to do WB_SYNC_NONE writeback from on-stack callers this will be nessecary. Also rename bdi_wait_on_work_clear to bdi_wait_on_work_done and inline a few small functions into their only caller to make the code understandable.

It turns out there are two bugs, the division-by-zero comes from a failure to deal with that in perf_calculate_period(). The other was more interesting and turned out to be a wrong comparison in perf_adjust_period(). The comparison was between an s64 and u64 and got implicitly converted to an unsigned comparison. The problem is that period_left is typically < 0, so it ended up being always true. Cure this by making the local period variables s64.

The way this is setup grew unwieldly and dso__load_vmlinux is the function that should allocate space for the long name, with callers not assuming that filenames should be allocated somehow by then (strdup, dso__build_id_filename, etc). For now this is the minimalistic patch, a proper fix for .36 will be made. Reported-by: Stephane Eranian <eranian@google.com> Tested-by: Stephane Eranian <eranian@google.com> Cc: David S.
