dquot_init() is never called in atomic context. This function is only set as a parameter of fs_initcall(). Despite never getting called from atomic context, dquot_init() calls __get_free_pages() with GFP_ATOMIC, which waits busily for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, to avoid busy waiting and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz> |
