Though g_vfs_close() is a wrapper around g_wither_geom_close(), r206130 added the following test in g_vfs_open(): if (bo->bo_private != vp) return (EBUSY); Which will cause a 'Device busy' error inside reiserfs_mountfs() if the same file system is re-mounted again after umount or mounting failure: (case 1, /dev/ad4s3 is not a valid REISERFS partition) # mount -t reiserfs -o ro /dev/ad4s3 /mnt mount: /dev/ad4s3: Invalid argument # mount -t msdosfs -o ro /dev/ad4s3 /mnt mount: /dev/ad4s3: Device busy (case 2, /dev/ad4s3 is a valid REISERFS partition) # mount -t reiserfs -o ro /dev/ad4s3 /mnt # umount /mnt # mount -t reiserfs -o ro /dev/ad4s3 /mnt mount: /dev/ad4s3: Device busy On the other hand, g_vfs_close() 'fixed' the above cases by doing an extra step to keep 'sc->sc_bo->bo_private' and 'cp->private' pointers synchronised.

Note that ext2fs doesn't support user settable append and immutable flags. EXT2_NODUMP_FL is an user settable flag also on Linux.

Do not retry request for the new block from ffs_bufwrite() when write is done from bufdaemon and there is a buffer shortage. In getnewbuf(), help bufdaemon to flush dirty buffers owned by the vnode locked by curthread. For MFC, default value for sysctl vfs.flushbufqtarget is set to -1, disabling the helpers. The TDP_BUFNEED flag value from HEAD conflicts with TDP_UPCALLING KSE bit, so it is moved to the end of allocated bits.
