Revision b23ff0e9330e4b11e18af984d50573598e10e7f9 authored by Mahesh Salgaonkar on 21 January 2010, 12:55:16 UTC, committed by Frederic Weisbecker on 28 January 2010, 13:15:51 UTC
On a given architecture, when hardware breakpoint registration fails due to un-supported access type (read/write/execute), we lose the bp slot since register_perf_hw_breakpoint() does not release the bp slot on failure. Hence, any subsequent hardware breakpoint registration starts failing with 'no space left on device' error. This patch introduces error handling in register_perf_hw_breakpoint() function and releases bp slot on error.
