* When forking a child process with PMC_F_DESCENDANTS set in pmc_attach()Bjoern A. Zeeb2015-08-241-3/+25
| | | | | | | | | | | | | | | | | | | | | | | | | in the parent, we will inherit the pmcids but cannot execute any operations on them in the child. The reason for this is that pmc_find_pmc() only tries to find the current process on the owners hash list, but given the child does not own the attachment, we cannot find it. Thus, in case the initial lookup fails, try to find the pmc_process state affiliated with the child process, lookup the pmc from there using the row index, and get the owner process from that pmc. Then continue as normal and lookup the pmc context of the owner (process). This allows us to call, e.g., pmc_start() in the child process before we start the work there, but to collect the accumulated results later in the parent.

* | account for ashift when gathering buffers to be written to l2arc deviceAndriy Gapon2015-08-241-13/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change that introduced the L2ARC compression support also introduced a bug where the on-disk size of the selected buffers could end up larger than the target size if the ashift is greater than 9. This was because the buffer selection could did not take into account the fact that on-disk size could be larger than the in-memory buffer size due to the alignment requirements. At the moment b_asize is a misnomer as it does not always represent the allocated size: if a buffer is compressed, then the compressed size is properly rounded (on FreeBSD), but if the compression fails or it is not applied, then the original size is kept and it could be smaller than what ashift requires. For the same reasons arcstat_l2_asize and the reported used space on the cache device could be smaller than the actual allocated size if ashift > 9. That problem is not fixed by this change. This change only ensures that l2ad_hand is not advanced by more than target_sz. Otherwise we would overwrite active (unevicted) L2ARC buffers. That problem is manifested as growing l2_cksum_bad and l2_io_error counters. This change also changes 'p' prefix to 'a' prefix in a few places where variables represent allocated rather than physical size. The resolved problem could also result in the reported allocated size being greater than the cache device's capacity, because of the overwritten buffers (more than one buffer claiming the same disk space).
