NAME

       generic_permission - check for access rights on a Posix-like filesystem

SYNOPSIS

       int generic_permission  (struct inode * inode, int mask,
                                 int (*check_acl) <funcparams>struct inode *inode, int mask</funcparams>);

ARGUMENTS

       inode  inode to check access rights for

       mask   right to check for (MAY_READ, MAY_WRITE, MAY_EXEC)

       check_acl
              optional callback to check for Posix ACLs

DESCRIPTION

       Used to check for read/write/execute permissions  on  a  file.  We  use
       ‘‘fsuid’’ for this, letting us set arbitrary permissions for filesystem
       access without changing the ‘‘normal’’ uids which are  used  for  other
       things..
