linux kernel - BUG: sleeping function called from invalid context at mm/slub.c:1719 -


i have allocated pointer 

int *ptr = kmalloc(sizeof(int), gfp_atomic);

and pointer deallocated in timer function having 5 second timeout value.

if( null != ptr )                 {                    kfree(ptr);   ptr = null; }

please advise me wrong here.. thanking in advance.

kfree() must not used in atomic context, such timer function.

move context, such workqueue.

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
