Is it a symlink? If it really doesn't exist, then there is no inode to match
against.
Oh...
No, there is no such file at all, and shouldn’t be, but apache2 tries to check it, hence
success=0 case is spammed into
then logs. Same with .htaccess files that apache2 tries to find in every directory...
I though it is possible to exclude stat calls with that path as argument to the syscall,
but if it actually needs
physical inode... then I guess it makes sense why it does not work for me.
I wanted to _ignore_ some known stat/open failures for non-existant files, to recap.
What kernel are you using?
3.2 and 3.16 for sure, and I believe I tested on Debian Testing so it should be 4.5
currently.
P.S. should I reply to all or just the list?
Thanks.
