INODE_CONGESTED(9) The Linux VFS INODE_CONGESTED(9)
NAME
inode_congested - test whether an inode is congested
SYNOPSIS
int inode_congested(struct inode * inode, int cong_bits);
ARGUMENTS
inode
inode to test for congestion (may be NULL)
cong_bits
mask of WB_[a]sync_congested bits to test
DESCRIPTION
Tests whether inode is congested. cong_bits is the mask of congestion bits to test and
the return value is the mask of set bits.
If cgroup writeback is enabled for inode, the congestion state is determined by whether
the cgwb (cgroup bdi_writeback) for the blkcg associated with inode is congested;
otherwise, the root wb's congestion state is used.
inode is allowed to be NULL as this function is often called on mapping->host which is
NULL for the swapper space.
