Subject: [PATCH] HACK: crucible: Work around kernel memory fragmentation
|
||||
|
||||
According to @Zygo:
|
||||
|
||||
> This will drastically reduce the number of reflinks bees can handle
|
||||
> to a single extent, but that size is beyond more than enough for most
|
||||
> filesystems. Making the buffer smaller may also reduce the size of
|
||||
> vmallocs which might be aggravating the kernel's memory manager.
