The bug is in the common fts(3) code, which assumes that there are no more subdirectories than the st_nlink field reports (minus two for . and ..). Th= is assumption is incorrect with ZFS, since it supports more subdirectories than fit in the st_nlink field's data type (nlink_t). As a result, fts(3) report= s to rm(1) that the subdirectories are not directories, and rm(1) tries to unlin= k(2) them, which fails with [EPERM]. In 12.0, nlink_t has been enlarged so it can report the correct number of subdirectories with ZFS, so this bug should no longer occur on that version. The fts(3) code in 11.x could be fixed in various ways as discussed in bug #197336. --=20 You are receiving this mail because: You are the assignee for the bug.=
