2019-06-01ocfs2: fix error path kobject memory leakTobin C. Harding
If a call to kobject_init_and_add() fails we should call kobject_put() otherwise we leak memory. Add call to kobject_put() in the error path of call to kobject_init_and_add(). Please note, this has the side effect that the release method is called if kobject_init_and_add() fails. Link: http://lkml.kernel.org/r/20190513033458.2824-1-tobin@kernel.org Signed-off-by: Tobin C.

2018-04-05ocfs2: add duplicated ino number checkGang He
Add duplicated ino number check, to avoid adding a file into the file check list when this file is being checked.

2018-04-05ocfs2: add kobject for online file checkGang He
Use embedded kobject mechanism for online file check feature, this will avoid to use a global list to save/search per-device online file check related data, meanwhile, reduce the code lines and make the code logic clear. The changed code is based on Goldwyn Rodrigues's patches and ext4 fs code.

2018-04-05ocfs2: fix some small problemsGang He
First, move setting fe_done = 1 in spin lock, avoid bring any potential race condition. Second, tune mlog message level from ERROR to NOTICE, since the message should not belong to error message. Third, tune errno to -EAGAIN when file check queue is full, this errno is more appropriate in the case.

2018-04-05ocfs2: move some definitions to header fileGang He
Patch series "ocfs2: use kobject for online file check", v3. Use embedded kobject mechanism for online file check feature, this will avoid to use a global list to save/search per-device online file check related data. The changed code is based on Goldwyn Rodrigues's patches and ext4 fs code, there is not any new features added, except some very small fixes during this code refactoring. Second, the code change does not affect the underlying file check code. Thank Goldwyn very much. Compare with second version, add more comments in the patch descriptions, to make sure each modification is mentioned. Compare with first version, split the code change into four patches, make sure each patch will not bring ocfs2 kernel modules compiling errors. This patch (of 3): Move some definitions to header file, which will be referenced by other source files when kobject mechanism is introduced.

2017-11-13Pass mode to wait_on_atomic_t() action funcs and provide default actionsDavid Howells
Make wait_on_atomic_t() pass the TASK_* mode onto its action function as an extra argument and make it 'unsigned int throughout. Also, consolidate a bunch of identical action functions into a default function that can do the appropriate thing for the mode. Also, change the argument name in the bit_wait*() function declarations to reflect the fact that it's the mode and not the bit number. [Peter Z gives this a grudging ACK, but thinks that the whole atomic_t wait should be done differently, though he's not immediately sure as to how] Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Peter Zijlstra <peterz@infradead.org> cc: Ingo Molnar <mingo@kernel.org>
