inode_congested — test whether an inode is congested
int inode_congested ( | struct inode * inode, |
int cong_bits) ; |
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.
