Waiman Long 9289012374 inotify: Increase default inotify.max_user_watches limit to 1048576 The default value of inotify.max_user_watches sysctl parameter was set to 8192 since the introduction of the inotify feature in 2005 by commit `0eeca28300` ("[PATCH] inotify"). Today this value is just too small for many modern usage. As a result, users have to explicitly set it to a larger value to make it work. After some searching around the web, these are the inotify.max_user_watches values used by some projects: - vscode: 524288 - dropbox support: 100000 - users on stackexchange: 12228 - lsyncd user: 2000000 - code42 support: 1048576 - monodevelop: 16384 - tectonic: 524288 - openshift origin: 65536 Each watch point adds an inotify_inode_mark structure to an inode to be watched. It also pins the watched inode. Modeled after the epoll.max_user_watches behavior to adjust the default value according to the amount of addressable memory available, make inotify.max_user_watches behave in a similar way to make it use no more than 1% of addressable memory within the range [8192, 1048576]. We estimate the amount of memory used by inotify mark to size of inotify_inode_mark plus two times the size of struct inode (we double the inode size to cover the additional filesystem private inode part). That means that a 64-bit system with 128GB or more memory will likely have the maximum value of 1048576 for inotify.max_user_watches. This default should be big enough for most use cases.

README

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.
