Certain management functions were being run at splbio() that had to be run at splvm(). * Adds a new feature to VN - swap space pre-reservation, in addition to the two features already added (zeroing and file creation/truncation). The swap space prereservation option may be used when configuring VN with swap backing store. Swap will be preallocated for all blocks in the device and no on-the-fly reallocation will occur. This avoids swap fragmentation and even allows you to 'recover' swap-backed VN-based filesystems across reboots provided that you create them with the same sizes and order as before and swap has not been allocated for anything else prior to the vnconfigs. A full description is available on my site. This patch has been extensively tested, especially the VN device when used in swap-backed mode. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
