2016-05-11f2fs: make atomic/volatile operation exclusiveChao Yu
atomic/volatile ioctl interfaces are exposed to user like other file operation interface, it needs to make them getting exclusion against to each other to avoid potential conflict among these operations in concurrent scenario.

2016-05-11f2fs: use mnt_{want,drop}_write_file in ioctlChao Yu
In interfaces of ioctl, mnt_{want,drop}_write_file should be used for: - get exclusion against file system freezing which may used by lvm snapshot. - do telling filesystem that a write is about to be performed on it, and make sure that the writes are permitted.

2016-05-11perf script: Fix export of callchains with recursion in db-exportChris Phlipot
When an IP with an unresolved symbol occurs in the callchain more than once (ie. recursion), then duplicate symbols can be created because the callchain nodes are never updated after they are first created. To fix this issue we call dso__find_symbol whenever we encounter a NULL symbol, in case we already added a symbol at that IP since we started traversing the callchain. This change prevents duplicate symbols from being exported when duplicate IPs are present in the callchain.

2016-05-11perf symbols: Add dso__insert_symbol functionChris Phlipot
The current method for inserting symbols is to use the symbols__insert() function. However symbols__insert() does not update the dso symbol cache. This causes problems in the following scenario: 1. symbol not found at addr using dso__find_symbol 2. symbol inserted at addr using the existing symbols__insert function 3. symbol still not found at addr using dso__find_symbol() because cache isn't updated. This is undesired behavior. The undesired behavior in (3) is addressed by creating a new function, dso__insert_symbol() to both insert the symbol and update the symbol cache if necessary. If dso__insert_symbol() is used in (2) instead of symbols__insert(), then the undesired behavior in (3) is avoided.

The commit b97511c5bc94 ("perf tools: Add overhead/overhead_children keys defaults via string") moved initialization of column headers but it missed to check the sort__mode. As 'perf diff' doesn't call perf_hpp__init(), the setup_overhead() also should not be called.
