Thanks! > Thanks! Success-aside, I was still noticing a lingering issue (fixed in the attached most-recent "watch_vop_remove3.d"). On "all night" runs, watching a tight-[infinite-]loop of "touch /tmp/foo; rm -f /tmp/foo", I was noticing this: dtrace: error on enabled probe ID 24 (ID 36603: vfs:vop:vop_remove:entry): invalid address (0xffffff80aa42ea00) in action #71 at DIF: offset 52 dtrace: error on enabled probe ID 24 (ID 36603: vfs:vop:vop_remove:entry): invalid address (0xffffff80aa8aea00) in action #110 at DIF: offset 52 dtrace: error on enabled probe ID 24 (ID 36603: vfs:vop:vop_remove:entry): invalid address (0xffffff80aa602a00) in action #93 at DIF: offset 52 dtrace: error on enabled probe ID 24 (ID 36603: vfs:vop:vop_remove:entry): invalid address (0xffffff80aa6daa00) in action #60 at DIF: offset 52 dtrace: error on enabled probe ID 24 (ID 36603: vfs:vop:vop_remove:entry): invalid address (0xffffff80aa7dfa00) in action #85 at DIF: offset 52 [snip 215 lines] dtrace: error on enabled probe ID 24 (ID 36603: vfs:vop:vop_remove:entry): invalid address (0xffffff80aa42ea00) in action #96 at DIF: offset 52 dtrace: error on enabled probe ID 24 (ID 36603: vfs:vop:vop_remove:entry): invalid address (0xffffff80aa8aea00) in action #135 dtrace: error on enabled probe ID 24 (ID 36603: vfs:vop:vop_remove:entry): invalid address (0xffffff80aa47fa00) in action #85 at DIF: offset 52 dtrace: error on enabled probe ID 24 (ID 36603: vfs:vop:vop_remove:entry): invalid address (0xffffff80aa8dba00) in action #110 at DIF: offset 52 dtrace: error on enabled probe ID 24 (ID 36603: vfs:vop:vop_remove:entry): invalid address (0xffffff80aa641a00) in action #85 at DIF: offset 52 dtrace: error on enabled probe ID 24 (ID 36603: vfs:vop:vop_remove:entry): invalid address (0xffffff80aa3efa00) in action #110 at DIF: offset 52 [more lines snipped] I read-up some more on the difference between variables and the costs associated with them (specific to FreeBSD; specifically that globals may have some locking issues and should be avoided). I made a new version of the script that changes all the variables to the clause-local syntax (this->), and that fixed the issue (no more spurious errors about invalid addresses). Please find attached latest watch_vop_remove3.d, potential candidate for commit to /usr/share/dtrace/. -- Cheers, Devin [-- Attachment #2 --] #!/usr/sbin/dtrace -s /* - * Copyright (c) 2014 Devin Teske <dteske@FreeBSD.org> * All rights reserved. * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.
