#3690: KDL when copying data to a FAT USB flash drive
------------------------------+---------------------------------------------
Reporter: haiqu | Owner: axeld

Platform: x86 | Blocking: 4066, 5362

Comment(by romain):
"dosfs_dir_flags.diff" fixes a bad assignment in the get_vnode hook. Since
the flags where not filled, they are randomly set to
B_VNODE_PUBLISH_REMOVED, i.e 1. This makes the vfs call the remove_vnode
hook, which removes the node fat entries. Later access to these nodes
trigger errors like the ones of ticket #5362.
Concerning the fat mirror patch, the buffer increment code was added when
porting the BeOS code to Haiku, and this can only be a mistake.
I will do more tests, but with these two patches, and #5340 I had no crash
until now; and Windows checkdisk is happy with my usb stick after 70MB of
file copy.
