Mainline Linux tree for various devices, only for fun :)
Running stress-ng on ocfs2 completely fills the kernel log with 'max lookup times reached, filesystem may have nested directories.' Let's ratelimit this message as done with others in the code. Test-case: # mkfs.ocfs2 --mount local $DEV # mount $DEV $MNT # cd $MNT # dmesg -C # stress-ng --dirdeep 1 --dirdeep-ops 1000 # dmesg | grep -c 'max lookup times reached' Before: # dmesg -C # stress-ng --dirdeep 1 --dirdeep-ops 1000 ... stress-ng: info: [11116] successful run completed in 3.03s # dmesg | grep -c 'max lookup times reached' 967 After: # dmesg -C # stress-ng --dirdeep 1 --dirdeep-ops 1000 ... stress-ng: info: [739] successful run completed in 0.96s # dmesg | grep -c 'max lookup times reached' 10 # dmesg [ 259.086086] ocfs2_check_if_ancestor: 1990 callbacks suppressed [ 259.086092] (stress-ng-dirde,740,1):ocfs2_check_if_ancestor:1091 max lookup times reached, filesystem may have nested directories, src inode: 18007, dest inode: 17940. ...

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
