When estimating working set size, measure only allocation batches, not free batches. Allocation and free patterns can be very different. For example, ZFS on vm_lowmem event can free to UMA few gigabytes of memory in one call, but it does not mean it will request the same amount back that fast too, in fact it won't. Update working set size on every reclamation call, shrinking caches faster under pressure. Lack of this caused repeating vm_lowmem events squeezing more and more memory out of real consumers only to make it stuck in UMA caches. I saw ZFS drop ARC size in half before previous algorithm after periodic WSS update decided to reclaim UMA caches. Introduce voluntary reclamation of UMA caches not used for a long time. For each zdom track longterm minimal cache size watermark, freeing some unused items every UMA_TIMEOUT after first 15 minutes without cache misses. Freed memory can get better use by other consumers. For example, ZFS won't grow its ARC unless it see free memory, since it does not know it is not really used. And even if memory is not really needed, periodic free during inactivity periods should reduce its fragmentation.

|4f592683||rmacklem||May 2, 2021, 11:04 p.m.||copy_file_range(2): improve copying of a large hole to EOF
PR#255523 reported that a file copy for a file with a large hole to EOF on ZFS ran slowly over NFSv4.2. The problem was that vn_generic_copy_file_range() would loop around reading the hole's data and then see it is all 0s. It was coded this way since UFS always allocates a data block near the end of the file, such that a hole to EOF never exists. This patch modifies vn_generic_copy_file_range() to check for a ENXIO returned from VOP_IOCTL(..FIOSEEKDATA..) and handle that case as a hole to EOF. asomers@ confirms that it works for his ZFS test case.
