NAME

lock_may_read - checks that the region is free of locks

SYNOPSIS

"SYNOPSIS"

int lock_may_read (struct inode * inode, loff_t start, unsigned long len);

ARGUMENTS

inode: the inode that is being read
start: the first byte to read
len: the number of bytes to read

DESCRIPTION

Emulates Windows locking requirements. Whole-file mandatory locks (share modes) can prohibit a read and byte-range POSIX locks can prohibit a read if they overlap.

N.B. this function is only ever called from knfsd and ownership of locks is never checked.
