The driver may sleep while holding a spinlock. The function call path (from bottom to top) in Linux 4.19 is: drivers/net/ethernet/intel/e1000e/mac.c, 1366: usleep_range in e1000e_get_hw_semaphore drivers/net/ethernet/intel/e1000e/80003es2lan.c, 322: e1000e_get_hw_semaphore in e1000_release_swfw_sync_80003es2lan drivers/net/ethernet/intel/e1000e/80003es2lan.c, 197: e1000_release_swfw_sync_80003es2lan in e1000_release_phy_80003es2lan drivers/net/ethernet/intel/e1000e/netdev.c, 4883: (FUNC_PTR) e1000_release_phy_80003es2lan in e1000e_update_phy_stats drivers/net/ethernet/intel/e1000e/netdev.c, 4917: e1000e_update_phy_stats in e1000e_update_stats drivers/net/ethernet/intel/e1000e/netdev.c, 5945: e1000e_update_stats in e1000e_get_stats64 drivers/net/ethernet/intel/e1000e/netdev.c, 5944: spin_lock in e1000e_get_stats64 drivers/net/ethernet/intel/e1000e/mac.c, 1384: usleep_range in e1000e_get_hw_semaphore drivers/net/ethernet/intel/e1000e/80003es2lan.c, 322: e1000e_get_hw_semaphore in e1000_release_swfw_sync_80003es2lan drivers/net/ethernet/intel/e1000e/80003es2lan.c, 197: e1000_release_swfw_sync_80003es2lan in e1000_release_phy_80003es2lan drivers/net/ethernet/intel/e1000e/netdev.c, 4883: (FUNC_PTR) e1000_release_phy_80003es2lan in e1000e_update_phy_stats drivers/net/ethernet/intel/e1000e/netdev.c, 4917: e1000e_update_phy_stats in e1000e_update_stats drivers/net/ethernet/intel/e1000e/netdev.c, 5945: e1000e_update_stats in e1000e_get_stats64 drivers/net/ethernet/intel/e1000e/netdev.c, 5944: spin_lock in e1000e_get_stats64 (FUNC_PTR) means a function pointer is called. To fix these bugs, usleep_range() is replaced with udelay(). These bugs are found by a static analysis tool STCheck written by myself.

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.
