This patch tries to make below macros calculating max inline size, inline dentry field size considerring reserving size-changeable space: - MAX_INLINE_DATA - NR_INLINE_DENTRY - INLINE_DENTRY_BITMAP_SIZE - INLINE_RESERVED_SIZE Then, when inline_{data,dentry} options is enabled, it allows us to reserve inline space with different size flexibly for adding newly introduced inode attribute.

This patch adds an ioctl to provide feature information to user. For exapmle, SQLite can use this ioctl to detect whether f2fs support atomic write or not. Reviewed-by:

When ->freeze_fs is called from lvm for doing snapshot, it needs to make sure there will be no more changes in filesystem's data, however, previously, background threads like GC thread wasn't aware of freezing, so in environment with active background threads, data of snapshot becomes unstable.

This patch resolves the below scenario. == Process 1 == == Process 2 == open(w) open(rw) begin write(new_#1) process_crash f_op->flush locks_remove_posix f_op>release read (new_#1) In order to avoid corrupted database caused by new_#1, we must do roll-back at process_crash time. In order to check that, this patch keeps task which triggers transaction begin, and does roll-back in f_op->flush before removing file locks. Reviewed-by:

When changing a file's acl mask, __f2fs_set_acl() will first set the group bits of i_mode to the value of the mask, and only then set the actual extended attribute representing the new acl. If the second part fails (due to lack of space, for example) and the file had no acl attribute to begin with, the system will from now on assume that the mask permission bits are actual group permission bits, potentially granting access to the wrong users. Prevent this by only changing the inode mode after the acl has been set. Signed-off-by:

This adds a perl script to actually parse the MAINTAINERS file, clean up some whitespace in it, warn about errors in it, and then properly sort the end result. My perl-fu is atrocious, so the script has basically been created by randomly putting various characters in a pile, mixing them around, and then looking it the end result does anything interesting when used as a perl script.

Prepping for scripting the MAINTAINERS file cleanup (and possible split) showed a couple of cases where the headers for a couple of entries were bogus. There's a few different kinds of bogosities: - the X-GENE SOC EDAC case was confused and split over two lines - there were four entries for "GREYBUS PROTOCOLS DRIVERS" that were all different things. - the NOKIA N900 CAMERA SUPPORT" was duplicated all of which were more obvious when you started doing associative arrays in perl to track these things by the header (so that we can alphabetize this thing properly, and so that we might split it up by the data too).

When setting up the Xenstore watch for the memory target size the new watch will fire at once. Don't try to reach the configured target size by onlining new memory in this case, as the current memory size will be smaller in almost all cases due to e.g. BIOS reserved pages. Onlining new memory will lead to more problems e.g. undesired conflicts with NVMe devices meant to be operated as block devices. Instead remember the difference between target size and current size when the watch fires for the first time and apply it to any further size changes, too. In order to avoid races between balloon.c and xen-balloon.c init calls do the xen-balloon.c initialization from balloon.c. Signed-off-by:

Commit dc6416f1 ("xen/x86: Call cpu_startup_entry(CPUHP_AP_ONLINE_IDLE) from xen_play_dead()") introduced an error leading to a stack overflow of the idle task when a cpu was brought offline/online many times: by calling cpu_startup_entry() instead of returning at the end of xen_play_dead() do_idle() would be entered again and again.

All in all, the bnxt_re, i40iw, and Dan Carpenter are 3/4 to 2/3rds of this pull request. There were some other random fixes that I didn't send in the last pull request that I added to this one. This catches the rdma stack up to the fixes from up to about the beginning of this week. Any more fixes I'll wait and batch up later in the -rc cycle. This will give us a good base to start with for basing a for-next branch on -rc2.

Pull powerpc fixes from Michael Ellerman: "A handful of fixes, mostly for new code: - some reworking of the new STRICT_KERNEL_RWX support to make sure we also remove executable permission from __init memory before it's freed. - a fix to some recent optimisations to the hypercall entry where we were clobbering r12, this was breaking nested guests (PR KVM). - a fix for the recent patch to opal_configure_cores(). This could break booting on bare metal Power8 boxes if the kernel was built without CONFIG_JUMP_LABEL_FEATURE_CHECK_DEBUG. - .. and finally a workaround for spurious PMU interrupts on Power9 DD2. Thanks to: Nicholas Piggin, Anton Blanchard, Balbir Singh" * tag 'powerpc-4.13-3' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/mm: Mark __init memory no-execute when STRICT_KERNEL_RWX=y powerpc/mm/hash: Refactor hash__mark_rodata_ro() powerpc/mm/radix: Refactor radix__mark_rodata_ro() powerpc/64s: Fix hypercall entry clobbering r12 input powerpc/perf: Avoid spurious PMU interrupts after idle powerpc/powernv: Fix boot on Power8 bare metal due to opal_configure_cores()
