NAME

SYNOPSIS

10

ARGUMENTS

12       inode
13           inode to check permission on
14
15       mask
16           right to check for (MAY_READ, MAY_WRITE, MAY_EXEC)
17

DESCRIPTION

19       Used to check for read/write/execute permissions on an inode. We use
20       “fsuid” for this, letting us set arbitrary permissions for filesystem
21       access without changing the “normal” uids which are used for other
22       things.
