Johannes Thumshirn 7e989f7062 scsi: sd_zbc: Use kvzalloc() to allocate REPORT ZONES buffer ... [ Upstream commit 7ce3e6107103214d354a16729a472f588be60572 ] We have two reports of failed memory allocation in btrfs' code which is calling into report zones. Both of these reports have the following signature coming from __vmalloc_area_node(): kworker/u17:5: vmalloc error: size 0, failed to allocate pages, mode:0x10dc2(GFP_KERNEL|__GFP_HIGHMEM|__GFP_NORETRY|__GFP_ZERO), nodemask=(null),cpuset=/,mems_allowed=0 Further debugging showed these where allocations of one sector (512 bytes) and at least one of the reporter's systems where low on memory, so going through the overhead of allocating a vm area failed. Switching the allocation from __vmalloc() to kvzalloc() avoids the overhead of vmalloc() on small allocations and succeeds. Note: the buffer is already freed using kvfree() so there's no need to adjust the free path.
