Subject: [PATCH] 9pfs: convert 'len/copied_len' field in V9fsXattr to the type
|
|
of uint64_t
|
|
|
|
The 'len' in V9fsXattr comes from the 'size' argument in setxattr()
|
|
function in guest. The setxattr() function's declaration is this:
|
|
|
|
int setxattr(const char *path, const char *name,
|
|
const void *value, size_t size, int flags);
|
|
|
|
and 'size' is treated as u64 in linux kernel client code:
|
|
|
|
int p9_client_xattrcreate(struct p9_fid *fid, const char *name,
|
|
u64 attr_size, int flags)
|
|
|
|
So the 'len' should have an type of 'uint64_t'.
|
|
The 'copied_len' in V9fsXattr is used to account for copied bytes, it
|
|
should also have an type of 'uint64_t'.
