__inode_permission9
Check for access rights to a given inode
Usage
int __inode_permission(struct inode * inode, int mask);
Arguments
inode
Inode to check permission on
mask
Right to check for (MAY_READ, MAY_WRITE, MAY_EXEC)
Overview
Check for read/write/execute permissions on an inode.
When checking for MAY_APPEND, MAY_WRITE must also be set in mask.
This does not check for a read-only file system. You probably want inode_permission.
