locks: print a warning when mount fails due to lack of "mand" support

2019-08-16T16:13:48+00:00

Since 9e8925b67a ("locks: Allow disabling mandatory locking at compile time"), attempts to mount filesystems with "-o mand" will fail. Unfortunately, there is no other indiciation of the reason for the failure. Change how the function is defined for better readability. When CONFIG_MANDATORY_FILE_LOCKING is disabled, printk a warning when someone attempts to mount with -o mand. Also, add a blurb to the mandatory-locking.txt file to explain about the "mand" option, and the behavior one should expect when it is disabled.

locks: add warning about mandatory locking races

2007-10-09T22:32:45+00:00

The mandatory file locking implementation has long-standing races that probably render it useless. I know of no plans to fix them. Till we do, we should at least warn people. Signed-off-by: J. Bruce Fields

Documentation: move mandatory locking documentation to filesystems/

2007-10-09T22:32:45+00:00

Shouldn't this mandatory-locking documentation be in the Documentation/filesystems directory? Give it a more descriptive name while we're at it, and update 00-INDEX with a more inclusive description of Documentation/filesystems (which has already talked about more than just individual filesystems).
