Finix1979 320f0c6022 Add Linux posix_fadvise support ... The purpose of this PR is to accepts fadvise ioctl from userland to do read-ahead by demand. It could dramatically improve sequential read performance especially when primarycache is set to metadata or zfs_prefetch_disable is 1. If the file is mmaped, generic_fadvise is also called for page cache read-ahead besides dmu_prefetch. Only POSIX_FADV_WILLNEED and POSIX_FADV_SEQUENTIAL are supported in this PR currently.
