2488--------------------------------------------------------
2489
2490This directory contains configuration options for the epoll(7) interface.
2491
2492max_user_instances
2493------------------
2494
2495This is the maximum number of epoll file descriptors that a single user can
2496have open at a given time. The default value is 128, and should be enough
2497for normal users.
2498
2499max_user_watches
2500----------------
2501
2502Every epoll file descriptor can store a number of files to be monitored
2503for event readiness. Each one of these monitored files constitutes a "watch".
2504This configuration option sets the maximum number of "watches" that are
2505allowed for each user.
2506Each "watch" costs roughly 90 bytes on a 32bit kernel, and roughly 160 bytes
2507on a 64bit one.
2508The current default value for max_user_watches is the 1/32 of the available
2509low memory, divided for the "watch" cost in bytes.
